Plain welded steel grating is the most popular steel grating solution for industrial flooring, platforms, walkways, and drainage systems. Manufactured by automatic resistance welding, it combines high load capacity, excellent drainage, and long service life in a durable one-piece structure. The smooth bearing bar surface is ideal for applications where slip resistance is not the primary requirement. Zhongzheng offers custom sizes, materials, bearing bar spacing, and surface treatments to meet ANSI, AS, EN, and other international standards for projects worldwide.
