Steel Grating [Source: Original] [Author: Anping steel joint steel grid MILL] [Date: 13-07-29] [Heat: 636] steel grating 1. Introduction: Our company produces such products are used flat steel rails in accordance with a certain distance and cross-arranged and welded into the middle of a steelworks with a square lattice, steel joint steel grid moderators use to do the drain cover, steel platform board, stepping ladders board, fence net. After crossbar commonly used twisted square steel. Steel Union Steel Grating commonly used carbon steel, hot dip galvanized appearance, can play a role in preventing oxidation. It may also be made of stainless steel. Steel grating with ventilation, lighting, cooling, slip-proof, drainage capacity and good performance 2, all models of our products are produced in accordance with the national standard processing (used in China for 2007 the latest version of Steel Grating standard) YB / T4001.1-2007 standards; in addition the United States, Britain, Australia and New Zealand also have their own standard steel standard according to GB700-88, GB1220-92 3, Steel Union Steel Grating show treatment: hot-dip galvanizing, cold galvanizing. painting, dip. I recommend customers the best hot-dip galvanized surface treatment process, such an approach appearance, good anti-corrosion effect, extend the life of the product 4, VAI pressure welding steel grating production methods: pressure welding steel grating by load flat steel and bars with certain distances, using 200 tons of hydraulic resistance welding automation equipment welded into the original plate, after cutting, opening, edging and other processes from customer requirements. Loaded flat pitch: two adjacent bearing bars by the center distance, common 30MM, 40MM two kinds. Bar spacing: distance between the centers of two adjacent rails is usually 50MM, 100, are two, according to customer requirements. 5, steel grating Features: beautiful appearance: simple lines. Silver exterior, modern trends. Best drainage: leakage area of ??83.3%, more than double the cast iron. Hot-dip galvanizing: rust-proof and strong, maintenance and replacement. Security design: box with hinged lid and connection, security, safe, easy to open. Saving investment: large span. When overloaded, the lowest ratio of iron and saves replacement costs stolen, then crushed. High strength: strength and toughness is much higher than cast iron, can be used for terminals, airports and other large span and heavy load environment. Specifications and more: meet different environment, load. Span, the size and shape desired. 6, a fixed method of grating can be used for welding and mounting clip fastening two ways. Advantages Steel Union Steel Grating Welding is permanently fixed, not loosen, the specific location on each corner of grating first root flat, weld length is not less than 20mm, height not less than 3mm of fillet welds. Advantages of convenient mounting clip destruction and removal of hot-dip zinc coating, each plate requires at least four sets of mounting clip, installation using clips with increasing the number of board length and increasing. The safest approach is not to lower clamp directly to the head of the screw in the beam welding, ensure that the steel grid plate mounting clip will not slip loose from the beam. 7, steel grating different purposes Series: VAI 1 Series (spacing 30mm) steel grating is the most common type, use of the product throughout the various industrial fields, this series of grating bearing bars center distance by 30mm compliance with US standards, the entire steel grating series, with the strongest impact on the surface resistance. It is widely used in power plants, refineries, sewage treatment plants, silos, chemical plants, highways, airports and so on dock platforms, walkways and drains cover, stair stepping and so on. Tooth steel grating which can be used in wet, slippery places, especially for offshore oil platforms. VAI 2 series (spacing 40mm) steel grating is the most economical and lightweight, in line with British standards for fixed platforms, walkways and stairs specifications, in a small span of occasions, this is the best product, even if in transit Under that kind of load device aisle is no exception, but also can be used for warehouse shelves, panels pavilion, bridge, protective fence, sun screens and so on. VAI 3 series (spacing 60mm) steel grating are varieties specifically for the application and development of the mining industry, it solves the mineral splash on the plate problem. This series of steel grating has a nominal size of 50 * 60mm through space to allow most of the spilled material wear off, thus ensuring a clean and safe plate surface, such products are often designated for use in the broken system board , conveying line walkways and ball mill, processing plant and operation station. 8. Packaging Steel Grating packaging, general packaging, there are three methods, one, packaged with bundling, generally applicable to relatively neat grid of steel plate. 2, lead screw fixation using four screws rods pass through aperture steel grating with screw locking guarantee methods. 3, tray ensure general for the export packing. Customers are mainly based on the circumstances, if the cargo is not much, we do not need with a forklift loading and unloading, and generally more convenient bulk. Conversely goods more generally packaged using forklift loading and unloading will be more convenient, in short, everything for the customer, which protect the product does not produce damage to cargo in transit shall prevail.
