Exceptional wind uplift strength

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

Saflok 410 concealed fix is an angular interlocking standing seam trapzoidal rib profile roll formed on mobile mills to any length. Cover width: 410mm. It is specifically designed for high wind load conditions.

Saflok 700 is a concealed fix profile, with an angular interlocking standing seam trapezoidal rib profile roll formed on mobile mills countrywide.

newlok

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

We produce the ever-appealing Corrugated and IBR profiles

We produce the ever-appealing Corrugated and IBR profiles under our proprietorial names of Tufdek® and Classicorr®, the brands being a mark of our quality assurance to you in roll forming and material standards. The innovative Versatile® profile combines the structural strength of a sheet with the aesthetic appeal of tile. 

Our exclusive IBR fix profiles include Widedek®, Trimflute® and Fluteline® for economical applications with wider sheet coverage.

The Corrugated profile is sinusoidal and can be used as roofing and cladding material. With its origins dating back to the Victorian era, it is probably the most commonly known sheeting profile used in the world today. The fact that the corrugated profiled sheeting has been around since before the turn of the century proves that this easy to use and effective profile for roofing and wall cladding is here to stay. Classicorr is the traditional and familiar S-Rib profile for roofing and cladding applications. The S-rib is derived from the sinus curve and offers very strong structural properties. The Corrugated profile virtually eliminates oil canning and the sheeting can be factory cranked, curved and bullnosed to various radii depending on customer’s requirements.

Fluteline is an angular trapezoidal fluted profile sheet with similar characteristics to IBR but having an effective cover of 889mm, which is wider than IBR.

IBR is an abbreviation for Inverted Box Rib, an angular trapezoidal fluted profile sheet with a bold appearance which makes it both attractive and practical. Tufdek has an effective covering width of 686 mm designed for use as side cladding or roofing material in commercial, industrial and residential buildings. The deep broad flute design offers excellent drainage characteristics combined with optimum weight versus load/span capabilities. Tufdek can be factory cranked, curved and bullnosed to various radii depending on customer’s requirements.

 

Is an angular trapezoidal fluted sheet and is similar in appearance to IBR profiled sheeting, the difference being the cover width of the sheet, and the depth of the flutes. Widedek sheeting has a cover width of 760mm and the depth of the flutes on Widedek is 28,5mm. The Widedek profile has a bigger cover width than IBR, resulting in a saving on sheeting.

The profile is roll-formed with 6 trapezoidal ribs at 203 mm, centres with a net cover of 1015 mm. The rib height shall be 26.5 mm and shall be fixed in accordance with the manufacturer’s recommendations.

Carefully selected to endure the harsh African climate

All the advantages of ZincAL® performance with the option of colour for added aesthetic appeal

COLORPLUS® is a factory pre-painted sheet with a ZincAL® substrate, giving you all the advantages of ZincAL® performance with the option of colour for added aesthetic appeal. COLORPLUS® is an appealing option for all building applications. The technologically superior paint system has been carefully selected to endure the harsh African climate with optimal colour-coating performance.

The paint used on COLORPLUS® limits chalking, and ensures optimal colour fastness.  The modified polymer system also helps to resist dirt or contaminant retention, ensuring that the building stays clean and the colour is fresh-looking for as long as possible.

COLORPLUS® is available in the following standard colours:

(Non-standard colours are available on request).

ZincAL®

World Class Coated Steel – Steel is the ultimate design material

Steel is the ultimate design material – light yet very strong, highly versatile, thermally efficient, fire resistant and yes, its green!

ZincAL® is a classic unpainted AZ coated steel, and COLORPLUS® is factory pre-painted onto a ZincAL substrate. When used in the correct application, you can be sure of:

  • Considerable increase in service life (due to 4 times greater corrosion resistance*)
  • Superior thermal performance
  • Lasting aesthetic value
  • The full technical backup of a globally recognised product produced in South Africa, and locally supported.**

* Global research has established that the performance of aluminium-zinc coated steel extends the service life of the steel core to 4 times longer than that of an equivalent Zinc galvanised sheet of the same coating thickness and used in the same application.

 

The technique of coating steel with an alloy of Aluminium and Zinc (55% Aluminium, 43.5% Zinc and 1.5% Silicon) has been extensively researched and the proven performance surpasses that of traditional galvanised steel.

 

bullnosing & cranking

Cranking of a profiled sheet incorporates lateral rib indentations pressed in at uniform distances which vary according to the radius requirements

PROFILE MINIMUM RADIUS (INSIDE CURVE)

SAFLOK 450mm 

WIDEDEK 350mm 

IBR 350mm 

CORRUGATED 350mm 

FLUTELINE 350mm 

NB. Negative (Reverse) Cranking on SAFLOK cannot be performed due to the nature of the profile. Please contact the manufacturer if any clarification is required. When ordering cranked sheets, details should be given using our standard information sheet 

EXPANSION It should be noted that Aluminium has an expansion co-efficient which is twice that of conventional steel substrates. If the sheet is to be bullnosed on one end, then expansion must be allowed for in the opposite direction. With the use of Saflok 700 this problem is reduced due to the fact that the profile will slide on the clip. 

NB. Profiles can be cranked in Full Hard and commercial quality material but only to a minimum radius of 400mm. SAFLOK 700 to a minimum of a 450mm radius. Cranking of a profiled sheet incorporates lateral rib indentations pressed in at uniform distances which vary according to the radius requirements. Cranked sheets can be supplied in standard radii as follows

STANDARD CRANK Normally with the narrow flute uppermost and the bend away from the angular inclination. 

REVERSE CRANK Normally with the narrow flute downward and the bend into the narrow flute. Applies to pierced fix profiles only
