BW Industries

If this is the first time you have heard of BW Industries, or you are a returning user, then we would advise you that we are a competitive alternative for steel components, particularly for our range of Purlins and Ancillary Components. BW Industries manufacture a range of Roof Purlins that can be supplied as Sleeved, Butted, Lapped or Heavy End Bay systems. The most popular purlin system we supply is the sleeved system but each application has its benefits. Our design software allows you to select the appropriate and most cost effective purlin system to suit each project and if assistance is required through the design process our Structural Engineer is on hand to offer advice. Our flexibility means that we offer one of the widest ranges of purlin sizes within the UK and we also offer bespoke cold rolled sections up to a massive 500mm deep x 6mm. Our steel roof purlins are supplied using pre-galvanised steels and have undertaken rigorous testing to achieve the SCI Assessed status. We can supply your purlins pre-punched to either a standard pattern or to your bespoke requirements. All of our steel roof purlins are made to order although we do have a small selection of galvanised purlins for sale – visit our news section for details. We can also press-form metal sections at lengths of up to 7300mm for products such as gutters, roof flashing, wall panels and grainwalling.

The oversail system with top flange cleats may be used where there are no restrictions on floor depth. The maximum allowable overhang should be no greater than one eighth of the adjecent span. All cleats are manufactured from pre-galvanised material as follows: Light duty cleats to be 3mm thick Standard duty cleats to be 4mm thick Heavy duty cleats to be 5mm thick

Punched with slotted holes to allow expansion at the side rail column connection. General Notes The rail or cleat is slotted longitudinally (14mm x 50mm) on the standard gauge lines. 60mm gap required between ends of rails. Fixing bolts to all joints must be fitted with a combustible washer, which will collapse under fire conditions, to allow movement for the rail to expand. The period of resistance is solely dependent on the cladding material used, and the type of construction. A certificate should be obtained from the cladding supplier. All primary structural steelwork, supporting the rails and cladding, should be fire protected.

If this is the first time you have heard of BW Industries, or you are indeed a returning user, then we would advise you that we are a competitive alternative for steel components and particularly for our range of Steel Framing of both Load Bearing and Non-Load Bearing sections.The market for steel framing is quickly expanding throughout the domestic, educational, commercial and industrial sectors. With its many benefits including speed of construction and erection, high strength and long life, it is fast becoming an economic and versatile alternative.

BW ‘Restraint’ or ‘Supporting’ ancillaries are incorporated to deter loading deformation of the side rails and assist in strengthening the overall structure when loaded with the side sheeting. All loading conditions are specifically calculated, only use BW products illustrated to ensure correct stability under wind pressure and suction loads.
