HSS Flat Bar Solid Metal Strip Metal Plate Trim 4 mm Thickness 200mm Length

For a standard shelf bracket repair, widths between 20mm and 40mm (0.79" – 1.57") are the most common fit. Measure the existing bracket face width and select the closest option. The 4mm thickness provides enough rigidity for light-to-medium shelf loads when the bar is bolted or welded in place.

A 4mm solid stainless steel flat bar has meaningful shear and bending resistance for light fabrication and DIY repair brackets. However, load-bearing structural applications — such as supporting overhead loads or safety-critical fixtures — should be independently assessed by a qualified engineer, as rated load capacity depends on span, fixing method, and load direction.

Stainless steel resists surface oxidation well in indoor and moderately damp conditions. In fully exposed outdoor environments — particularly coastal or high-humidity areas — the grade of stainless steel affects long-term corrosion resistance. If you need confirmation of the specific alloy grade for your environment, please contact us before ordering.

Yes. A standard angle grinder fitted with a stainless-rated cutting disc, or a hacksaw with a fine-tooth blade, will cut through 4mm stainless cleanly. For drilling, use HSS-Co (cobalt) or carbide-tipped drill bits at a slow speed with cutting fluid to prevent work-hardening. Standard MIG/TIG welding with stainless filler wire is also compatible.

Stainless steel can be used alongside mild steel, though galvanic corrosion may occur at contact points in wet environments — isolating washers or sealant are recommended in those cases. Direct contact with aluminium in damp conditions can accelerate corrosion of the aluminium; use an isolating barrier where this is a concern.

Narrow bars (6–16mm) suit applications like hinge reinforcement, cable guides, thin spacers, and edge trim where a low profile is needed. Wider bars (40–100mm) are better for flat mounting plates, reinforcement gussets, and structural repair patches where surface area and bending resistance matter. When in doubt, measure the contact face of the part you are repairing or replacing and match it as closely as possible.
