Waterway drainage grid heavy-duty spliced steel grate

Waterway drainage grid heavy-duty spliced Steel Grate

Steel grate is suitable for alloys, building materials, power stations, and boilers. shipbuilding. Petrochemical, chemical, and general industrial plants, municipal construction, and other industries have the advantages of ventilation and light transmission, non-slip, strong bearing capacity, beautiful and durable, easy to clean, and easy to install. Steel grate has been widely used in various industries at home and abroad, mainly used as industrial platforms, ladder pedals, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, three-dimensional Parking lots, fences of institutions, schools, factories, enterprises, sports grounds, garden villas, can also be used as external windows of houses, balcony guardrails, guardrails of highways and railways, etc.

   Details of steel grate   

The Heavy Duty Steel Grate is a kind of Construction Mesh that is cross-arranged with flat steel according to a certain distance and cross bars (twisted square steel, square steel, round steel, flat steel, etc.), and welded into a square grid in the middle. The board is mainly used as the cover board of the ditch, the steel structure platform board, the step board of the steel ladder, etc.
The crossbar is generally made of twisted square steel. The steel grate is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. Can also be made of stainless steel. Steel grate has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.

Steel grating models can be divided into two types: standard and non-standard: for example G325/30/100, where 325 means that the load-bearing flat steel is 32*5mm, 30 means that the load-bearing flat steel spacing is 30mm, and 100 means twisted bars (horizontal bars) The spacing is 100mm.

1. Standard specification 30A series: G203/30/100 G253/30/100 G303/30/100 G323/30/100 G255/30/100 G305/30/100 G325/30/100 G405/30/100 G455/30 /100 G505/30/100 40A series: G203/40/100 G253/40/100 G303/40/100 G323/40/100 G255/40/100 G305/40/100 G325/40/100 G405/40/100 G455/40/100 G505/ 40/100 30B series: G203/30/50 G253/30/50 G303/30/50 G323/30/50 G255/30/50 G305/30/50 G325/30/50 G405/30/50 G455/30/50 G505/ 30/50 40B series: G203/40/50 G253/40/50 G303/40/50 G323/40/50 G255/40/50 G305/40/50 G325/40/50 G405/40/50 G455/40/50 G505/ 40/50 The standard steel grating also includes various specifications of flat steel (applicable to the above four series), the flat steel spacing is 60mm, the twisted rod spacing is 200mm and other combinations.

2. Non-standard flat steel of various specifications, the free combination of bearing flat steel spacing of 25, 34, 35, 45mm, twisted rod (cross bar) spacing of 38, 76mm.
 
In addition, various inter-insert and inter-insert steel gratings also belong to the list of non-standard steel gratings. Open holes, curved plates, and circular plates are also non-standard steel gratings.

   Application of steel grate   

The steel grate is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel. The steel grate has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.

Steel grate is a kind of steel product with a square grid in the middle that is cross-arranged with flat steel according to a certain spacing and cross bars, and welded by a pressure welding machine or manually to form a square grid in the middle. The steel grating is mainly used as a ditch cover , steel structure platform board, step board of steel ladder, etc. The cross bar is generally made of twisted square steel.
