After the galvanized steel grating and the steel grating are produced, they should be treated with rust prevention. There are two types of hot-dip galvanized and electro-galvanized. The standard of hot-dip galvanizing is: GB/T 13912-2002 Technical requirements and experimental methods of hot-dip galvanizing of steel products. As a new material and new product, steel grating is being widely used. The price-performance ratio shows the prospect of its application.

There are two kinds of galvanized steel gratings that we often say: pay attention to the distinction

Hot-dip galvanizing - also known as hot-dip galvanizing, it melts zinc ingots at high temperature, puts in some auxiliary materials, and then immerses the metal structural parts into the galvanizing tank, so that a layer of metal components adheres to it Zinc layer. The advantages of hot-dip galvanizing lie in its strong anti-corrosion ability and good adhesion and hardness of the galvanized layer. The weight of the product increases after galvanizing. The amount of zinc we often talk about is mainly for hot-dip galvanizing.

"Cold plating"----"electroplating", that is, the zinc salt solution is electrolyzed to make the iron ions and zinc ions exchange and reflect. Generally speaking, no heating is required, and the amount of zinc applied is very small. It is easy to rust in a humid environment. .

Explanation of special terms for galvanized steel grating

Steel grating is an open-plate steel member that is made up of load-bearing flat steel and crossbars at a certain distance orthogonally combined and fixed by welding or press-locking. According to different production methods, it is mainly divided into pressure welded steel grating and compressed steel grating.

Bearing Flat Bar: The flat bar that bears the main load

Crossbar: twisted square steel, round steel or flat steel fixed on the load flat steel

Clearance: The maximum inscribed circle diameter of the open through hole of the steel grating.

Flat bar center-to-center distance: the distance from the center to the center of two adjacent load-bearing flat bars.

Crossbar center spacing: the distance between the center to center of two adjacent crossbars.

Hemming plate: flat steel or section steel welded to the steel grating bearing flat steel or other openings and cut edges

Skirting board: a baffle that is fixed around the platform or on the edge of the cutout and opening of the steel grating.

Length of steel grating: the maximum dimension of the steel grating parallel to the direction of the bearing flat steel, called the length of the steel grating (L)

Steel grating width: the maximum size of the steel grating perpendicular to the direction of the bearing flat steel, called the width of the steel grating (W)

Scope of application of galvanized steel grating

Steel grating is suitable for alloys, building materials, power stations, boilers. shipbuilding. For petrochemical, chemical and general industrial plants, municipal construction and other industries, it has the advantages of ventilation and light transmission, anti-skid, strong bearing capacity, beautiful and durable, easy to clean and easy to install. Xinqiao steel grating has been widely used in all walks of life at home and abroad, mainly used as industrial platforms, ladder treads, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drain covers, manhole covers, road grilles , Three-dimensional parking lot, the fence of institutions, schools, factories, enterprises, sports fields, garden villas, can also be used as the exterior windows of houses, balcony guardrails, highways, railway guardrails, etc.

Purchasing Considerations

Nowadays, steel gratings are more and more widely used in our daily life, and then hot-dip galvanized steel gratings are also used in the actual process. However, it is particularly important to distinguish the true and false of hot-dip galvanized steel gratings.

(1) The center spacing of hot-dip galvanized steel grating flat steel: according to the series: series 1 is 30mm; series 2 is 40mm; series 3 is 60mm.

(2) The center spacing of the cross bars of hot-dip galvanized steel grating: series 1 is 100mm, series 2 is 50mm. Other specifications can be customized.

(3) Hot-dip galvanized steel grating flat steel: The material is Q235A or stainless steel, and there are ordinary flat type, anti-skid tooth type and section I type. Common specifications are 20*5, 25*5, 25*3, 32*5, 32*5, 40*5, 40*3, 50*5, 65*5, 75*6, 100*8, 100*10 Wait.

(4) Hot-dip galvanized steel grating crossbar: round steel, twisted square steel, square steel or hexagonal steel made of Q235A or 304 stainless steel. Twisted square steel is drawn and twisted by a square die, and its commonly used specifications are 5*5, 6*6, 8*8mm, etc. These are the four major characteristics that distinguish real and fake hot-dip galvanized steel gratings.

Galvanized steel grating types: steel grating, steel grating, glass fiber reinforced plastic grating, galvanized steel grating, ditch cover, gutter cover, hot-dip galvanized steel grating, stainless steel grating, platform steel grating Panels, composite steel gratings, plug-in steel gratings, steel grating ceilings, stair treads, etc.
