Safintra excels at Steel Awards 2022

by Media Xpose

The 2022 SAISC Steel Awards was the first in-person awards ceremony held since the start of the Covid-19 pandemic. The event, which demonstrates excellence in the use of steel in construction, reaffirmed the resilience of the local steel industry sector over the past two years and celebrated the innovation, ingenuity and sense of community within the steel construction industry.

SAISC CEO Amanuel Gebremeskel commented on the number of high-quality, truly excellent projects that were showcased at this year’s annual Steel Awards. Safintra’s Saflok 700 concealed fix and Newlok standing seam profiles once again featured prominently in a number of winning projects.

‘House Benoni’ wins in two categories

Winner of two categories – Residential and Best Project Gauteng – was House Benoni, a residential home. House Benoni demonstrated innovative use of steel, combined with all the other elements of construction to deliver a statement piece of architecture and a warm, welcoming family home. Safintra’s elegant standing seam profile, Newlok, completed the high visual impact of this stunning showpiece by adding a crisp modern look and feel to this high-end residence.

The main contractor on the project, Dave Monro of Monro Roof Sheeting, commented: “A great deal of time was spent in discussion with the client regarding finishes. We set out to build an award-winning house. Newlok delivers an excellent aesthetic effect, and the wide pans allow for a very pleasing finish to the vertical and angular cladding. It is very versatile and one of the best standing seam roofing products available on the South African market.”

Freshmark: Best Project Limpopo

Winner of Best Project Limpopo, was Freshmark, a distribution centre in Polokwane. The project made use of particularly innovative cladding: atypical of a warehouse building, and technically challenging to achieve. The result was aesthetically pleasing, with a design element of curved bullnoses from roof to cladding. Safintra’s concealed fix roofing profile Saflok 700 was used for the project.

Johann Walters of Van der Linde Venter Projects, the main contractor on the project commented, “Safintra inspected the installation and the manufacturer carried out an inspection of the coating to ensure the quality was acceptable, giving the client peace of mind.”

Several finalists also used Saflok 700

Several other projects which used Saflok 700 were finalists in the Steel Awards. These included:

  • ACDC Dynamics, Cape Town: A flagship warehouse, distribution centre and retail store. 
  • Drakenstein Sentrum, Paarl, Cape Town: A boutique retail mall.
  • Imperial Health Logistics, Gauteng: A warehouse-design facility. This project received commendations in the metal cladding and roofing category.
  • Getworth, Cape Town: A vehicles signature showroom.

What is concealed fix roofing and what makes it exceptional?

Safintra’s concealed fix roof sheeting has attained its position as the preferred system for long-span or low-slope roofs due to its versatility, durability and proven functionality.

These systems are ideal for long length sheets on industrial and commercial buildings and have also become extremely popular in high-end residential applications, allowing for the construction of eye-catching roofing systems which were never previously possible with traditional pierced fixed profiles and tiles.

Well-designed concealed fix roofing and cladding solutions can handle the most robust of weather conditions with ease and offer superior performance under foot traffic and associated roofing workloads.

One of the main benefits of concealed roof sheeting is that the sheets are secured to the purlin with a clip system from underneath and are not pierced with any fasteners. The clips which are required to fix the sheets to the purlins serve two purposes:

  1. They sidestep the need for holes in the sheet (which prevents the possibility of leakage through perforation).
  2. When faced with changing thermal conditions the roof is allowed to expand and contract in a sliding movement over the clips which helps to prevent tearing around the fastener points.

The only solution for large-span metal roofs

In large-span metal roofing applications, concealed fix systems are the only choice. Considering the size of investment concerned in these applications, the engineering performance of the entire roofing and cladding “system” is critical.

Concealed fix systems enable professional teams to reliably serve the long-term interests of their clients and reduce liability for all concerned. Modern, large span projects dictate the innovative use of concealed fix systems. Designs are increasingly becoming more bold, daring even, and a feverish pursuit of sustainability seems to dominate the realm of architectural design. It is in exactly this nuanced space, that concealed fix systems can contribute massively towards sustainability and a solid return on the client’s investment.

Steel used is 100% recyclable

The steel used in concealed fix profiles is 100% recyclable, and modern coating technologies render the roof much cooler than what was conventionally achievable.

The latest polyester paints display unsurpassed colour stability with cutting-edge technologies being applied to ensure maximum effectiveness and reflectivity under harsh UV elements. These modern adaptations of traditional technology take a massive leap towards sustainability – without compromising economical prudence.

The secret to robust concealed fix solutions is in the clip

When it comes to concealed fix roofing, the design of the clips is of paramount importance. The clip serves as the “anchor” which secures the sheet to the sub-structure and holds it down in all weather conditions.

The material and thickness of the clip helps to determine its inherent strength, which in turn determines the minimum wind-uplift resistance requirements for a particular roof.

The overall “system” design defines the manner in which the clip locks into the sheet profile. The clip should engage every rib of the profile to prevent wind cushioning under the unsecured rib and distorting the sheet off the clip.

As a general rule, the more ribs that are secured with a positive clasp holding it to the purlin, the stronger the wind-uplift resistance. If not positively secured, the ribs should be shaped to provide a strong and stable interlock with the clip at every point. A complete system will also offer a high wind load detailing for particular terrain categories or design parameters such as wide overhangs.

Additional benefits of concealed fix roofing systems

  • Aesthetically pleasing with no visible fasteners on the roof.
  • Versatile application on both high pitched roof slopes and almost flat roofs.
  • Watertight roofs with no exposed fixings and therefore less prone to leakage.
  • No limit to the length of the roof sheet as roof sheets that exceed transportable lengths can be rolled on site to provide a fit for purpose solution.
  • No end laps eliminate potential for ingress at laps along with accelerated corrosion.
  • Outstanding thermal and acoustic performance.
  • Can be used in conjunction with Green Roof systems.
  • Increasingly secure with non-visible fixtures preventing easy removal to gain access to a building.
  • Roof sheets can be disassembled and recovered for later use.
  • Ideal for rainwater harvesting.

Safintra’s concealed fix roofing profiles

Safintra offers three concealed fix roofing profiles, Saflok 700, Saflok 410, and Newlok, a standing seam profile.

Saflok and Newlok are both concealed fix and secret fix profiles as the anchoring system is not visible. This allows unrestrained thermal expansion and contraction. The difference between concealed fix (Saflok) and standing seam (Newlok) is that the Newlok profile can be seamed either mechanically or by hand, giving it additional wind hold-down capability.

Saflok concealed fix roofing is the most widely specified system available. The precisely engineered clip and the dimensional consistency of the Saflok profiled sheet provide a robust and reliable roof system. Over 10-million square metres of this sheeting have been installed over the past three decades in South Africa alone – underlining Saflok’s proven track record and best-in-class credentials.

Saflok 700

Saflok 700 is the most advanced wide coverage concealed fix system on the market with a cover width of 700mm per sheet for fast, cost-effective installation. The profile’s re-engineered clips ensure superb sheet engagement at every rib, and total stability at the male-female lap while its deep pans allow for excellent water run-off, even at a 2° pitch.

The profile has achieved significant market share over the past 30 years and has a proven track record. Saflok 700 has an unapologetically rugged yet aesthetically pleasing design, and its components include detailing for both high wind loads and structurally challenging installations

Saflok 410

Saflok 410 is Safintra’s flagship product within the concealed fix market. It has an effective cover width of 410mm and is an angular interlocking trapezoidal rib profile which can be roll-formed on site.

The key to Saflok 410’s unmatched performance is the interaction between the profile’s innovative geometric design and the performance of its second-generation clip. This winning formula has proven itself in the testing grounds of the Western Cape and Eastern Cape where typically high wind loads have allowed Safintra to build up a track record for the Saflok 410 profile as truly the best in its class.

The Saflok 410 roofing system has been independently tested at the Council for Scientific and Industrial Research (CSIR) by Dr Adam Goliger, widely regarded as the leading engineer in the field of wind upliftment and as one of the pioneers of topographical wind environmental studies. During the tests, the profile excelled in the following:

  • Exceptional uplift performance and serviceability (ideally suited to push the boundaries of modern design criteria).
  • Exceptional point load carrying ability (reduced damage due to foot traffic and the subsequent installation of rooftop items such as HVAC or solar panels which impose point loads).


Newlok is a concealed fix, standing seam profile with an effective cover width of 445mm and a rib height of 50.8mm.

It is designed for use on low pitched roofs and can withstand high wind conditions in industrial, commercial and residential applications. Newlok’s unique interlocking clipping system incorporates a concealed cleat to positively hold down the male-female joint at every rib.

The two-part cleat allows for natural thermal expansion and contraction of the sheet, while the rib height delivers optimal water shedding capabilities at slopes as low as 1.5°. The profile can be roll-formed by a mobile mill on the building site, in continuous lengths.

Safintra now has mobile mills across the country

Safintra’s award-winning concealed fix profiles are the preferred choice among professionals in the South African construction industry. These profiles have proven their worth over the past decades in high wind environments, giving owners complete peace of mind that their roofing system will remain structurally sound for far longer than its competitors.

Safintra now has mobile mills across the country and roofing sheets can be ordered in any length required although on-site rolling is recommended for lengths in excess of 13.2 metres due to practical transportation requirements. Safintra’s best-in-class concealed fix profiles are backed by a full Safintra warranty and are available countrywide.

As a professional, you should demand full technical details of the system you intend to specify and request technical support throughout the installation itself. Safintra is proud to offer this service free of charge to all its customers from seven branches countrywide.
