3. TOPSPAN 22 Light, strong, economical TOPSPAN® 22 steel ceiling battens are versatile and easy to use, providing strength, lightness and rigidity with low cost. TOPSPAN 22 is a 22mm deep profile used as a ceiling batten for internal fixing of ceiling and wall liner. It is compatible with all popular domestic plasterboards. The top flange of the profile has an embossed surface to make it easier for the plasterboard screws to grip and ‘bight-in” without slippage during awkward installation positioning. The lips of the bottom flanges are rounded for improved safety during handling and installation...

4. TOPSPAN 40 TOPSPAN 40 is a 40mm deep profile used as a roofing batten for residential tiled roof or steel roof. It is commonly called a “roofing batten”. The top flange of the profile has an embossed surface to make it easier for the steel roofing screws to grip and ‘bightin” without slippage during awkward and steep installation angles (up to 25 degrees). Furthermore the embossment improves the slip resistance when the roofers are walking up the roof structure during the placement of the roof tiles or steel roofing. The lips of the bottom flanges are rounded for improved safety during handling...

5. TOPSPAN 61 TOPSPAN 61 is a 61mm deep profile used in the smaller framed shed and awnings market and is a convenient size to satisfy the niche market need of a section between a small purlin and large batten. It is popular in the residential and rural markets and has found other applications such as framing, long-span plasterboard battens, fencing and handyman applications. It is commonly called a “garage batten”. The bottom flanges have two longitudinal stiffeners/grooves for improved performance, but also act as a guide for the correct positioning of the fixing fasteners. Lapping (structural)...

6. TOPSPAN 96 TOPSPAN 96 is a 96mm deep profile used as a roof purlin or wall girt. It is largely used in the rural market for shed, however has application for residential garages and awnings. It is commonly used in-lieu of the smaller and lighter gauge traditional Cee and Zed purlins, and is conveniently sized to be between the TOPSPAN 61 and TOPSPAN 120. The bottom flanges have two longitudinal stiffeners/grooves for improved performance, but also act as a guide for the correct positioning of the fixing fasteners. The webs have a single longitudinal stiffener for improved web strength and...

7. TOPSPAN 120 TOPSPAN 120 is a 120mm deep profile used as a roof purlin or wall girt. It is commonly used in the rural, residential and small commercial market for shed, garages and awnings where longer spans or strength is required. It is commonly used in lieu of the smaller and lighter gauge traditional Cee and Zed purlins. It is commonly called a “rural purlin”. It’s versatility has resulted in applications other than a purlin such as shelving and flooring. The top flange of the profile has two longitudinal stiffeners/grooves for improved performance. In some applications these grooves are...
