Application and requirements of steel grating in shipbuilding industry

Due to its light weight, high strength and convenient installation, the steel grating has been widely used in the shipbuilding industry. It has been extensively adopted in the ship's machine and furnace channel, deck channel, overhaul channel and platform, etc. The standard of the shipboard steel grating is CB / T608 -1998, steel grating commonly used 32 * 3,40 * 3,50 * 5 flat steel production. The use of different environments and uses, marine steel grating is often made of stainless steel and aluminum alloy manufacturing.

Marine steel grating requirements:

1, Grating size deviation, should meet the requirements of YB 4001-9l.

2, steel grating manual welding, welding with double-sided 3mm, the end of the package angle welding, there should be no leakage welding, Weld and bite meat phenomenon.

3, steel grating 娤 welding should be calibrated straight.

4, steel grating is made, the surface should be shiny, no sharp edges, burr spatter.

5, steel grating manufacturing and surface treatment requirements should be consistent with the requirements of YB 4001-9l

6, steel grating manufacturing allow deviation, length. Width ± 3mm, diagonal is 3mm. Flatness of not more than 3mm.

7, BC-type steel grating manual assembly, the adhesive brushing should be uniform, no glue out, the appearance of clean and tidy.

After the steel grating is made, there should be no burrs, cracks and other defects.

9, steel grating color should be uniform.

10, steel grating safety load bearing 300 kg, the disturbance is 2mm below.
