Description
A 3m length of L shaped profiled box section: a 30 x 40mm zinc coated steel box with a single 15mm flange along one edge, 45mm wide overall. The box is folded from 1.5mm steel sheet, and the flange is folded double to 3mm, so it is stiff and has no sharp single-sheet edge. It is made for framing composite and timber gate boards and fence infill, where the box gives the frame its strength and the flange gives a ledge on one side for the board ends to sit on and fix to, leaving the other side of the box clean. It weighs about 5.5 kg. The price shown is for one 3m length.
Why choose this section
A ledge on one side only. The single 15mm flange carries the board ends while the other side of the box stays plain, which is what you want on the outer edge of a frame, a hanging or closing stile, an end post or a corner.
Folded double flange. The flange is two thicknesses of sheet, 3mm in all, with a rounded folded edge rather than a cut edge.
Light but stiff. The closed 30 x 40mm box resists bending far better than flat strip or angle of the same weight, and 5.5 kg per 3m is easy to handle on your own.
Zinc coated. A bright zinc finish over the whole section, so it is protected before you start and ready to paint once the frame is made.
Where it is used
Outer frames, stiles, end posts and corners for composite board gates and fence panels, slatted screens and bin stores, shed and garden structure framing, board-on-frame cladding, and general light fabrication where a box with fixing flanges saves cutting and welding separate angle.

Cutting and fitting
Measure and cut to length with a metal cutting disc, band saw or fine-tooth hacksaw, then deburr and touch up the cut ends with zinc-rich paint. Fix or weld the box into your frame, then sit the board ends on the flange and screw through them with self-drilling screws. Weld in a ventilated space, as zinc coated steel gives off fumes when welded.
Frequently asked questions
Is the price for one length?
Yes, for one 3000mm length. For larger quantities, call us for a quantity price.
How wide is it overall?
45mm: the 30mm box plus the 15mm flange.
Can I paint it?
Yes. Clean and degrease it, use a primer made for zinc coated steel, then top coat.
Can I weld it?
Yes, with care as it is 1.5mm sheet. Use a low heat setting, and weld in a ventilated space because of the zinc coating.
