Description
A 3m length of 40 x 8mm mild steel flat bar, hot rolled and supplied bare. Straight plain bar stock for gates, railings, brackets and general fabrication, ready to cut, drill, weld, bend and paint. Each length weighs about 7.1 kg. The price shown is for one 3m length.

Why choose this bar
A wide, heavy flat. 40mm wide and 8mm thick gives room for bolt holes side by side and a stiff rail or plate that will not flex.
Easy to work. Mild steel cuts, drills, taps, bends and welds cleanly with ordinary workshop tools and MIG, TIG or stick welding.
A full 3m length. Long enough for gate and railing rails with little waste, and easy to cut down for short parts.
Bare and ready to finish. No coating to grind off before welding, so you prime and paint or galvanise once the work is made.
Where it is used
Gate and railing rails, heavy brackets and base plates, fence post straps, ties and braces, ladder and step stringers, trailer and machine repairs, and general fabrication.

Cutting, welding and finishing
Cut with a metal cutting disc, band saw, chop saw or hacksaw, and deburr the cut. It drills cleanly with HSS bits. Clean off mill scale where you weld. Bend small sizes cold in a vice or bender, or heat larger sizes for tight bends. To finish, wire brush or grind off loose scale, degrease, prime with a metal primer and top coat, or have the finished work hot-dip galvanised.
Frequently asked questions
Is the price for one length?
Yes, for one 3000mm length. For larger quantities, call us for a quantity price.
Is it painted or galvanised?
No. It is bare hot rolled steel and will rust if left outside unprotected, so prime and paint it or galvanise it once your work is made.
Can you cut it to length?
It is supplied in 3m lengths. Call us before you order if you need it cut, and we will tell you what we can do.
