General Introduction

Aluminum grating has excellent corrosion resistance, light weight and beautiful appearance. It’s widely used in marine engineering, ships, machinery, decoration, etc.

Press-locked grating is made if pre-punched bearing bars and flush top cross bars, fit them to each other’s pre-punched slot with hydraulic pressure, bearing bar and cross bar are integrated rigidly. It performs better load capabilities than swaged bar gratings and it provides a smooth and clean appearance. Compared with press-welded grating, it posses the same characteristics with none welding spots and better artistic looking. 

Technical Data

•Material: T6061, 6063 alloy, ASTM B221•Bar grating made up of interlocking perpendicular bars.

•Bearing bar sizes range from 1" x 1/8" through 2-1/2" x 3/16" in 1/4" increments.

•Bearing bar spacing of 1-3/16", 15/16", 11/16" and 7/16" c.c. with cross bar spacing of 4" or 2".

•Hydraulic pressure is used to bond the slotted bars together, locking the deep cross bar into the notched bearing bar.

•Smooth, clean look due to a flush top rectangular cross bar.

•Offers strong lateral stability.

•Used in architectural design because of clean look and tight spacing.

•1/4" and 1/2" openings.
