Introduction
Steel grating 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. Steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.
Steel grating is a kind of steel product with a square grid in the middle, which is made of flat steel arranged crosswise with a certain spacing and horizontal bars, and welded by a pressure welding machine or manually. Gutter cover, steel structure platform plate, steel ladder tread, etc. Crossbars generally use twisted square steel
Uses
Steel gratings are 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.
Series classification of steel gratings for different uses: Series (spacing 3) steel gratings are the most commonly used type and are used in various industrial fields. The center distance of the loaded flat steel of this series of steel gratings is 3, Complying with American standards, it has the strongest resistance to surface impact among the entire steel grating series. It is widely used in platforms, walkways and drain covers, stair steps, etc. in power plants, refineries, sewage treatment plants, granaries, chemical plants, highways, airports and docks. Among them, the toothed steel grating can be used in wet and slippery places, especially suitable for offshore oil production platforms. Series (spacing) steel grating is the most economical and lightweight type, complying with the specifications of fixed platforms, walkways and stairs stipulated in British standards. It is the most ideal product in situations with small spans, even in transportation equipment walkways. It is no exception under load. It can also be used as warehouse shelves, pavilion panels, trestles, protective fences, sun curtains, etc. Series 3 (spacing) steel grating is a variety specially developed for applications in the mining industry. It solves the problem of mineral splashing on the plate. This series of steel gratings has a nominal size of * ventilation, allowing most of the splashed materials to pass through, thus ensuring the cleanness and safety of the plate surface. This product is often specified for use in the plate surface of the crushing system, conveying Online walkways and ball mills, processing plants and operation stations, etc. As a new engineering material, steel grating is mainly used as platforms, trestles, bridges, highway guardrails, trench covers, fences, gates and other facilities in the fields of metallurgy, energy, shipping, municipal administration, petrochemicals, transportation, building materials, national defense and other fields. At present, my country's annual demand for steel grating is approximately 10,000 tons. Therefore, the market prospect of steel grating is very broad.
Packaging
There are generally three packaging methods for steel grating packaging: packing with strapping, which is generally suitable for fixing the steel grating with screw rods that are relatively neat. A screw rod is passed through the aperture of the steel grating. The screw locking guarantee method is pallet guarantee, generally for export packing. It mainly depends on the customer's situation. If the goods are not large and do not need to be loaded and unloaded with a forklift, bulk packaging is generally more convenient. On the contrary, if there are a lot of goods, it will be more convenient to use general packaging for forklift loading and unloading. In short, everything is for the convenience of the customer and to protect the products from damage during transportation.
Surface treatment
Hot dip galvanizing, cold galvanizing, spray painting, dipping in anti-rust oil, dipping in plastic, no treatment.
Structure
The steel grating is composed of load-bearing flat steel and horizontal bars arranged at a certain distance in longitude and latitude. The longitude direction is the load-bearing flat steel, that is, the length direction of the steel grating is the horizontal bar. That is the width direction of the steel grating.
Note on welding
At each intersection point of the load flat steel and the cross bar, it should be fixed by welding, riveting or pressure locking.
For the welding of steel gratings, pressure resistance welding is preferred, and arc welding can also be used.
For the pressure locking of steel grating, a press can be used to press the cross bar into the load-bearing flat steel to fix it.
. Steel gratings should be processed into various sizes and shapes according to the needs of users.
The spacing between the load-bearing flat steel bars and the cross-bars can be determined by the supply and demand parties according to the design requirements. When building an industrial platform, it is recommended that the spacing between load-bearing flat steel bars should not be greater than 1, and the spacing between crossbars should not be greater than 1.
