Trench cover [Source: Original] [Author: Anping VAI steel grid MILL] [Date: 13-07-29] [heat: 252] trench cover my steel mill production of steel grid linking trench cover points To: drain cover and trench cover two series. VAI drain cover drains and water wells for steel joint trench cover for cable trenches and road ditch. The shape of the trench cover is divided into ordinary type, pressure-locking, anti-theft can be opened and angle edging type. Our brand trench cover the full range of products, according to the different needs of customers, customize different models, styles and trench cover drain cover. According to ditch cover the use of different environments we can do for its hot-dip galvanized, painted, epoxy, plastic, injection and painted asphalt surface treatment; you can also use stainless steel in accordance with the special circumstances, brass, aluminum for production. Advantages Steel Union trench cover is simple construction, light weight, carrying, impact, rather bend do not break, displacement of large, strong corrosion resistance, beautiful and durable. These unique advantages are an incomparable cast iron cover, trench cover common type trench cover common type of flat steel for production use different depending on the load requirements. Usually made of flat steel Q235 Material: 25 * 5,30 * 5,32 * 5,40 * 5,50 * 5,60 * 5, flat pitch using 30mm or 40mm; crossbar using twisted square steel 6 * 6, and 8 * 8, 10 * 10, the spacing usually 50mm or 100mm; pressure by large solder equipment for welding, cutting, edging, galvanized or painted processes produced. When installed on both sides need to ditch slotted, laying flat or angle iron, steel grating after completion of the laying of the ride at a preset slot. It should be noted that the measurement gap to reserve trench width, we usually cover the production scale will ditch 5mm, as is easy to install. Pressure lock type steel joint press trench cover lock type trench cover for heavy load area, such as docks, workshops, factory and other places need too heavy vehicles. So the pressure is also called heavy load lock trench cover trench cover, trench cover lock Steel Union pressure on flat steel production process is slotted according to certain rules, and then plug compression, welding, plastic, galvanized and other processes made . VAI is characterized by heavy loads trench cover mesh size were associated with, each bite, beautifully harmonious, elegant, strong carrying capacity. Walking for high-density, pressure-locking trench cover heavy vehicles, cargo trucks and other occasions need larger size flat steel production, steel joint press lock groove decking with 40 * 4.50 * 5.60 * 5 80 * 8,100 * 8,100 * 10,150 * 12 flat steel production, cover the length of not more than 1m. Trench cover is generally square or rectangular hole hole, hole size is 40 * 40 * 50 or 100 is more commonly used specifications. Third, the anti-theft alarm trench cover VAI trench cover, trench cover is embedded anti-theft, also called stormwater sewer grate, drain covers. Such products in the civil pouring concrete inside the frame, welded or soldered door hinge axis Production, easy to open, and has a good anti-theft capabilities. So this type of trench cover, also known as anti-theft trench cover, applicable to municipal roads, parks, gardens, residential areas, schools, colleges, sports stadiums and other public places. Many of its features: displacement of a large, easy to open dredging, hot galvanized corrosion preventive ability to super, beautiful delicate appearance. Angle edging style trench cover (GU steel grating trench cover) steel mill steel grid associated with the production angle edging trench cover products, mainly for the hotel kitchen cooking, rodents, and easy to clean. Marble floor, does not destroy the original ground, laying simple. Stairs with a small grid, no card heel. Union steel trench cover this need to prepare in advance, directly resting on the edge of the ditch on both sides of the installation is simple and convenient. Such steel grating trench cover are generally smaller flat pitch, usually 15mm, 20mm, 25mm and 3mm of four, the bar usually 30mm, 50mm or 100mm. Because the area does not need to apply much capacity, so the use of flat steel are generally small, flat steel commonly used specifications: 20 * 3,25 * 3,30 * 3,32 * 3,35 * 3,40 * 3,30 * 4,40 * 4,25 * 5,30 * 5,32 * 5,35 * 5,40 * 5 * 5 and 50. Using our advanced steel grating pressure welding solder equipment, after cutting, edging, galvanized and other processes produced. Plug can also be used for production of steel grating. Union steel production this trench cover pavement simple, beautiful, no pollution, no rot stainless.
