12mm Dense Welded Steel Walkway Grating Galvanized Bar Grating For Workshop
Galvanized Flat Steel Space 12mm Dense Welded Steel Walkway Grating for workshop
Description:
Dense steel grating is a kind of welded steel grating with the spacing of bearing flat steel less than 25 mm. It is mainly used in the occasion have higher request for gratings.
Galvanized Steel Walkway Grating is the product in accordance with customers requirements that is lined by load flat steel and horizontal rod alternately in a certain space, welded into primary plate in the high voltage resistance welding machine, then through the deep-processing of such working procedures as cutting, slitting, tapping, bordure, etc.
For example:1.The wheel of the baby carriage can not fall from dense steel grating.
2.Dense steel grating slope
3.Dense steel grating floor.
4.Dense steel grating corridor
5.Dense steel grating as mezzanine
6.Dense steel grating as platform.

Specific application:
Steel grating products are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering, and they offer the following the features:
Specification: The space of flat steel is 12 mm or 20 mm, the spacing of horizontal pole is 30 mm or 50 mm.
Feature: In addition to having the advantage of appearance form and easy installation, Dense steel gratings also meet the request of special occasion pass through or leave out object size. For example, where the larger flow, can demand the request of Ms. high-heeled shoes walk; for industrial and mining enterprises, the request of doesn't allowing large objects (such as the steel ball of the diameter less than 10 mm) leave out.
Application: Main used for the occasion have higher request of steel grating, such as, ships, drilling platforms, offshore platforms, walkways, etc. to prevent objects falling. Also used factory aerial work platforms and high-level working platform shop, avoiding wound by the high-altitude litter.
