Types of gratings
Gratings by material
Stainless Steel
How they are made
Electro-forged gratings are resistance-welded under pressure. Press-locked gratings have cross bars pressed into notched bearing bars. Panels are banded, cut to size and hot-dip galvanised (carbon steel) or pickled (stainless).

Frequently asked questions
Electro-forged or press-locked grating?
Electro-forged gratings are the economical, robust standard for industrial platforms. Press-locked gratings give a neater appearance and flexible bar spacing for architectural use.
Which materials are gratings available in?
Stainless Steel: 2 grades in total, from stock or mill-sourced.
What sizes of gratings do you supply?
Bearing bars 20 × 3 mm to 100 × 10 mm; pitch 30 – 60 mm (bearing) × 50 – 100 mm (cross); panels to size.
How are gratings tested?
Load and deflection per manufacturer tables; Galvanising thickness; Weld and dimensional inspection.
