SAFLOK 700 CLIP LAUNCH - KwaZulu Natal April 2018
On the 20th April 2018, Safintra Durban hosted an educational morning for Architects during which the company showcased its revolutionary new Saflok 700 Clip. Hosted at the well-known ‘Village Table’ restaurant in Umhlanga the event was attended by over 70 architects from the greater Durban area. Guest speaker Philip Thornhill from TC Design Architectsstarted off the morning with an inspiring insight into his working life as an architect, and shared some tricks of the trade learnt during his illustrious career.
He was followed by Justin Jackson, Sales and Operations Manager of Safintra South Africa; who delivered a high impact talk on concealed fix roofing, and highlighted the advancements that have taken place recently including development of the newly redesigned and re-engineered Saflok 700 Clip which outperforms all others.
The presentation included pictorials, severe weather systems that have recently been experienced in South Africa, and which demonstrated the applications for the new Saflok 700 Clip.
The CPD presentation was also delivered by Justin Jackson and based on feedback was very well received. The presentation is accredited by the South African Institute of Architects for its educational merit, and to see the guests taking extensive notes during the talk spoke volumes of the excellent content.
Congratulations to the Safintra Durban team for hosting this successful event.

The highlight of the structural steel industry calendar, the 36th Annual Steel Awards hosted by SAISC (South African Institute of Steel Construction) was held on 13 September 2017. Garnering 56 entries from over 300 tems for projects demonstrating excellence in steel construction, this year's awards delivered on every front. Safintra South Africa sponsored the Factory and Warehouse category, while the overall winner for 2017 was announced to be the BMW H-EMS Roof Lift, submitted by Teichmann Structures – the main contractors for the project. In addition to being named overall winner, this project also won the Safal Steel Innovation Category.
South Africa embraces a variety of architectural styles, from Cape Dutch and French Huguenot to Tuscan and English. Some work, some do not, some are timeless, some are trite. But one fact is a game changer – the need to look at sustainability in the built environment. And steel roofing is leading the charge for change.
Roofing needs to rise to the challenges posed by global warming, the move to eco-neutrality, the rising cost of energy and the financial returns required by an investor.
Metal roofing has impeccable sustainability credentials, and its versatility makes it the material of choice for stunning architecture from modern to traditional. But it is functional performance that sets it apart.
A building is always an investment. So durability and the lifetime costs of occupation and ownership are critical. So too is its impact on the well-being of the people who live and work in it, and the way it uses resources. Quality components which are correctly installed in a well-designed roofing system offer returns that are financial, social and environmental.
The Safintra Innovations Roadshow will unpack a basket of best-of-breed components, which make up a metal roof system that delivers returns for the full occupied life of the building – each component separately warranted but when used together, the system stands apart.
- For increasingly violent weather, Safintra has a new generation Saflok clip system for concealed fix roofing.
- For energy-efficiency, Safintra has clamps that will make the roof a source of power without compromising the performance or warranty of the roof sheeting.
- To minimise maintenance costs, Safintra offers fasteners which will have a life expectancy longer than that of the roof sheeting.
- To reduce energy costs and lower the environmental impact, Safintra offers an over-roofing and roof spacer system which ensures the insulation you buy gives you the performance you paid for.
- And to reduce its environmental impact, Safintra has the long-span Metsec steel purlin system.
Finally, Safintra will warrant the integrated roof system for performance – thermal, functional and durability. That is a game changer.

One important item is the weight of the roofing system. Today’s available roofing materials include a wide range of weights. For comparison, let’s look at the weight of one “square” of various products. A “square” covers 100 square feet of roof area.
- ALUMINUM: 40 – 70 pounds
- STEEL: 80 – 125 pounds
- COPPER: 100 – 125 pounds
- COMPOSITE / POLYMER PANELS: 150 – 275 pounds
- FIBERGLASS / ASPHALT SHINGLES: 275 – 425 pounds
- CONCRETE TILE: 400 – 700 pounds
- SLATE: 900 – 1300 pounds
- CLAY TILE: 1100 – 2000 pounds
Why Does Roof Weight Matter?
The weight of a roofing material, when carefully considered, can be a significant portion of your roofing decision.
Weight impacts key areas of overall roof performance
AGING STRUCTURES. As a structure ages, it weakens. Structural lumber may crack and foundations may move. A low weight roof system can prolong the structure’s life and integrity. A case in point is the First United Methodist Church in Sidney, Ohio. This impressive, looming structure had a clay tile roof that was about 80 years old when, at great expense, the decision was made to remove the tiles, clean them, put new underlayment on the roof, and re-install the tiles. Just a couple of years after this work was done, a major beam snapped above the sanctuary. It was unable to handle the weight of the roof.
SEISMIC ACTIVITY. In areas prone to seismic activity, heavy roofing can cause structures to slide off their foundations or even collapse. Lower weight products can be a good choice as much earthquake damage is sustained by structures with heavy roofs.
HIGH WINDS. Regardless of its weight, properly secured roofing materials can meet even the most strict wind uplift requirements. In the case of catastrophic storms, very heavy weight roofing materials pose a huge risk if they become airborne.
FIRE RISK. Many types of roofing materials are designed to resist combustion from exterior fires. However, most home fires start inside the structure. Firefighters are heavily trained in the risks of entering homes with heavy roof systems once the fire reaches the attic. Heavier roofs create a greater risk of collapse that could trap firefighters inside the structure. This means that firefighters have to contain the fire from the outside rather than enter the building and try to stop the fire.
RAW MATERIAL USE. Roofing materials come, in one way or another, from natural resources. The heavier the roofing material is, the more pounds of our natural resources are being consumed in order to create it.
TRANSPORTATION COST. Heavier weight roofing materials require additional fuel for transportation. With a low weight roofing material, as many as 300 squares or even more may fit on a semi-truck but weight limitations can hold that to 20 – 30 squares for very heavy roofing materials.
ENERGY EFFICIENCY. Heavy roofing materials typically have great thermal mass. While this thermal mass can offer some nominal R Value, it also holds heat. This means that summer heat absorbed by the sun can be held by the roof and continue to keep your attic hot even after the sun goes down.
The use of aluminium-zinc coated steel as a practical cladding material is gaining popularity along the coast of Africa.
Bounded by three oceans and the Mediterranean Sea, Africa has a vast coastline of 26 000km. Its deep rivers and natural ports have been historically important trading hubs and remain as vibrant nodes of urban settlement and business.
The populations of this vast coastline are blessed with abundant natural materials for building, but increasingly, as new infrastructure development booms, the use of metal as a practical, durable cladding material is taking off.
The Safal Group is the sole licensee of aluminium zinc coating technology in Africa and sells its coated steel sheeting along 12 000km of this coastline, down the eastern seaboard from Djibouti to South Africa in the extreme south, and up westward to Luanda in Angola.
All coated steels are not the same
Steel plays a huge role in development, but it does have an inherent weakness – when used unprotected and exposed to the environment, it rusts and corrodes. To extend the service life of steel, it is generally protected with a corrosion-inhibiting coating.
The two most commonly used coatings to protect steel are:
- Aluminium zinc coating (AZ) – aluminium and zinc.
- Galvanised coating (GI) – zinc.
The addition of aluminium to zinc in the coating alloy extends the service life of a steel roof by up to four times that of galvanised steel.

Made for Africa’s coastline
Aluminium zinc coating technology, developed in the 1960s in North America, enabled coated steel to deliver a service life of decades, even in aggressive coastal conditions. This development revolutionised the metal cladding industry, and is today the most widely used coating technology worldwide.
In Africa this coated steel is branded Zincal and its factory colour-coated derivative is called Colorplus, produced in Africa at three coating mills owned by the Safal Group.
The thicker the coating, the longer is the resistance to corrosion and the longer the life of the protected steel substrate, and a coating of 54 microns on Zincal Ultima gives it corrosion-proof performance credentials which are suitable for coastal areas where only aluminium sheeting was previously specified.
Taking a challenge head-on
In Safintra’s book of achievements, there is nothing better than a challenging project. This includes challenging locations, weather and most of all, the challenge of trying out a new product.
One such a challenge was the recent application of Safintra products at a newly-installed solar array on the Wild Coast.
Saflok 700 roof sheeting was rolled in aluminium 0,8mm material, transported to the location, installed and then over-fitted with Safintra S-5 roof clamps, onto which the solar panels were secured. Forming part of the approved range of Safintra Roofing System components, Safintra’s S-5 clamps do not void the warranties on the roofing material. This proved to be a critical factor in the financial feasibility of the project. To consider replacing part of the roofing system in this location, even 15 years down the road, was not an option. Safintra’s S-5 clamps are warranted for 25 years and have pull-out loads which are unbeaten worldwide.
The Saflok roofing profile has proven its performance as a sealed roofing system many times and aluminium was the ideal material to use in a location within 2km of the Wild Coast’s shoreline.
Another significant challenge was the timing on the project. Within two weeks, the roof sheeting was produced in the Durban plant of Safintra and loaded on a flatbed truck with clips, fasteners and other hardware. The clamps were put through final loading tests in Denver, Colorado.
A Safintra technical expert, as well as an S-5 technical expert from the USA, was present to ensure the correct installation of the sheeting and the clips above it, and the perfect alignment on solar panels on top of the lot.
Day 3: Tuesday
The S-5 clamps were put through final loading tests in Denver, Colorado, and test videos were sent to the client on the Wild Coast by satellite cellphone.
Day 2: Wednesday
Dustin Haddock left Denver, with the still-warm clamps in his luggage, for 20 hours of travelling.
Day 1: Thursday
Dustin was met by Marnitz Benecke of Safintra in Johannesburg for a late flight to Durban.
An early start from Virginia airstrip in a small plane, on site by 10am, finished by 3pm and back on the plane to Durban that evening.
The project was an immense success, and despite the long travelling hours, Safintra congratulated the team – in the Unites States and South Africa – on a job well done.

Who says it isn’t possible to have the best of both worlds? The look and feel of a traditional tile roof with the GREEN credentials, thermal efficiency, cost saving and lightweight properties of steel – It is possible with Safintra Roofing’s unique profile – Versatile.
Safintra Roofing celebrates its twenty first anniversary this year and has marked the event with a series of new product launches – amongst them the launch of the Versatile 5 profile, a wider version of the company’s Versatile 4 profile.
Use of this profile has exploded onto the South African market and particularly in the province of KwaZulu-Natal, where it has been used on a number of Department of Public Works developments. Tafadzwa Togarasei of leading Durban Architecture firm, DGIT Architecture explains: “I think the popularity of the Versatile profile can be attributed to a number of factors. Firstly, its aesthetic appeal. The beauty of this profile is that it indeed gives you the look of conventional roof tiles. More and more emphasis is being placed on the environment and sustainable building. Steel roofing is by far the most environmentally friendly option available. It is also a fact that in construction time is money. If you have a high quality product that meet standards and saves you time, on procurement, installation and maintenance, then that product is bound to be a winner. This product also enables us to lower the roof structure costs. Its availability in sheet form allows us to make use of fewer trusses, sometimes getting away with half the trusses that would have been required when using conventional roofing tiles. Transport costs are also reduced because a large quantity of sheeting can be delivered in one single delivery. Improved metal coating technology, such as Aluminium-Zinc coatings ensures that our clients have a quality maintenance free product with a superior lifespan.”
DGIT Architecture has specified the Versatile profile on a number of KZN Developments, specifically for the Department of Public Works. These developments include the Department of Education’s Empangeni Rail (Richem) Secondary School and Birdswood Secondary School in Richards Bay. The company has also specified the profile on a number of projects for the Department of Health.
Safintra Roofing’s National Marketing Manager, Sally Stromnes: ”We are extremely proud to add the Versatile 5 profile to our already extended range. We have had excellent reviews from our customers and feel that as more emphasis is being put on designing buildings that conform to environmentally high performing buildings and building materials, the use of steel will escalate. Apart from its obvious economical and environmental benefits steel roofing is also perfectly suited to the harvesting of rainwater, which we believe will become an area of key focus. Going forward, we as a company are committed to providing environmentally friendly solutions to the building industry with innovative products, such as Versatile 5”.
