Serrated bar grating is welded with a serrated surface. In addition to the general characteristics of ordinary steel structures, serrated bar grating has a strong anti-slip ability, which is especially suitable for wet, slippery areas and offshore oil platforms. 

Serrated bar gratings are usually treated with a hot dip galvanized surface. This surface provides strong rust protection for the serrated grid plate.

 Serrated bar grating can be used as a drain cover that can be hinged to the frame for greater safety, safety and ease of opening.

Serrated bar grating is made of high-strength carbon steel and has high strength. The strength and toughness of high carbon steel zigzags is much higher than that of cast iron grille covers. It can be used for the construction of airports and other large spans and heavy loads. The product has a large spacing and good drainage. The leakage area is 83.3%, which is twice than thef cast iron gratings. This steel grille has a large span and a simple profile that saves material.

 

Material 

There are four main material types

First, ordinary flat steel: the material is Q235 steel. Common common models are 253, 255, 303, 305, 323, 325, 403, 404 405, 503, 505, 605, 705 and other specifications. We use flat steel mainly by cutting and cutting.

Second, serrated steel: a model similar to ordinary steel. The only difference is that it has a tooth side. Mainly used for non-slip surfaces.

Third, I type steel: thick plates on both sides, thin in the middle.

The fourth material is twisted steel or twisted square steel. Generally 5x5 6x68x8 square steel, twisted steel.

 

Serrated bar grating series type (mainly based on spacing): 

Series 1 (pitch 30mm)Serrated bar gratings are the most common type used in various industrial applications. The center of the loaded flat bar is 30mm, which meets US standards. In this steel grille series, this 30 mm steel grille has the highest resistance to surface impact. It is widely used in power plants, refineries, sewage treatment plants, silos, chemical plants, highways, airports and container terminal platforms, walkways and gutter covers, stair treads, etc. The sawtooth steel grille can be used in wet, smooth areas, especially for offshore oil platforms.

 

Series 2 (40mm pitch) steel grilles are economical and lightweight, built to the British standard for fixed platforms, walkways and stair sizes. This is ideal for small occasions, even in transport aisles. It can also be used for warehouse shelves, gazebo boards, bridges, protective fences, sun visors, etc.

 

Series3 (pitch or pitch 60mm) flat or serrated steel grids are designed for the application and development of the management industry. It solves the problem of mineral splashing on the board. The steel grille has a nominal size of 50 * 60mm, allowing most of the spilled material to ensure a clean and safe surface. 60mm pitch steel panel products are typically specified for broken system boards, transmission line corridors and ball mills, processing plants and operating stations.

Serrated bar grating uses:

Serrated bar gratings are widely used in petroleum, chemical, port, electric power, transportation, paper, pharmaceutical, steel, food, municipal, real estate, manufacturing and other fields.
