Steel grating is an open steel component that is orthogonally combined with load-bearing flat steel and cross bars at a certain distance and fixed by welding or pressure locking; the cross bars generally use twisted square steel or round steel. Or flat steel, the material is divided into carbon steel and stainless steel. Steel grating is mainly used to make steel structure platform plates, trench cover plates, steel ladder treads, building ceilings, etc.
Steel gratings are generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. It can also be made of stainless steel. Steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.
Steel grating specifications
Steel grating is composed of flat steel and twisted steel crossbars. Commonly used flat steel specifications are: 20*3, 20*5, 30*3, 30*4, 30*5, 40*3, 40*4, 40*5, 50*5, etc. Special flat steel specifications can be customized. Crossbar diameter: 6mm, 8mm, 10mm.
Steel grating uses
Steel grating is suitable for alloys, building materials, power stations, and boilers. shipbuilding. It is used in petrochemical, chemical and general industrial plants, municipal construction and other industries. It has the advantages of ventilation and light transmission, anti-slip, strong bearing capacity, beautiful and durable, easy to clean and simple to install. Steel grating has been widely used in various industries at home and abroad. It is mainly used as industrial platforms, ladder treads, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, three-dimensional Fences in parking lots, offices, schools, factories, enterprises, sports fields, garden villas, and can also be used as exterior windows of residential houses, balcony guardrails, highway, railway guardrails, etc.
Steel grating surface treatment methods
Steel grating can be hot-dip galvanized, cold-dip galvanized, painted or without surface treatment. Among them, hot-dip galvanizing is a commonly used method. The appearance is silvery white, bright and beautiful, and has stronger corrosion resistance. The price of cold galvanizing is relatively low, and the use time is between 1-2 years. It is easy to rust when encountering humid environment, and is generally used indoors. Spray painting is also cheap and has a variety of colors to choose from. This treatment is generally used to match the color of surrounding objects. Steel gratings can also be made without surface treatment, and their prices are lower.
Steel grating features
Simple design: No need for small support beams, simple structure, simplified design; no need to design detailed drawings of steel gratings, just indicate the model, and the factory can design the layout plan on behalf of the customer.
Anti-dirt accumulation: Does not accumulate rain, ice, snow and dust.
Reduce wind resistance: Due to good ventilation, wind resistance is small in strong winds, reducing wind damage.
Light structure: less material is used, the structure is light, and it is easy to hoist.
Durable: It has been hot-dip galvanized for anti-corrosion treatment before leaving the factory, and has strong resistance to impact and heavy pressure.
Modern style: beautiful appearance, standardized design, ventilation and light transmission, giving people an overall smooth modern feeling.
Durable: It has been hot-dip galvanized for anti-corrosion treatment before leaving the factory, and has strong resistance to impact and heavy pressure.
Save construction period: The product does not require on-site reprocessing and installation is very fast.
Easy construction: Use bolt clamps or welding to fix the pre-installed supports, and it can be completed by one person.
Reduce investment: Save materials, save labor, save construction period, and eliminate cleaning and maintenance.
Material saving: The most material-saving method under the same load conditions. Correspondingly, the material of the supporting structure can be reduced.
