Silicon Metal Description Silicon metal is also called crystalline silicon or industrial silicon. The deoxidation efficiency of silicon metal is very high, and it is often used as the raw material of ferrosilicon alloy. In steelmaking production, silicon metal can increase furnace temperature, increase molten iron fluidity, and improve the toughness and cutting ability of castings. Silicon metal 441 has a higher silicon content. So it can be used as an iron alloy additive in the steelmaking industry. The price of silicon metal 441 is higher than metal silicon metal 553, but the quality is better. Silicon metal grade 441 Application: 1. The main use of silicon metal is as an additive for non-ferrous alloys. 2. Alloying agent for demanding silicon steel. 3. Silicon metal is a good component in aluminum alloys, and most cast aluminum alloys contain silicon.

Safety step bar grating is used for ladder rungs, side door trailer steps, stirrup steps and other safe truck access applications made of aluminum, carbon steel, galvanized steel and stainless steel. We supply safety step grating at 20' long pieces and cut to sizes. Maximum length available for stainless steel grating is 120". Flooring Safety Metal Bar Grating, designed to support heavier loads than plank grating, used for trucks, trenches, mezzanines, walkways, work platforms, and industrial floors.

Expanded metal grating is the most practical and economical mesh panels to assure strength, safety, and a non-skid surface, which requires almost no maintenance. Expanded metal grating is ideal for use on plant runways, working platforms, and catwalks, as it is easily cut into irregular shapes and can be installed quickly by welding or bolting. We supply expanded steel and metal grating panels for pedestrian and light vehicle traffic and other load bearing applications. Compared with bar type gratings, expanded steel sheets offer more pattern designs. Expanded Steel Grating serves popularly in following constructions: Ramps; Flooring; Platforms , ; Walkways; Treads; Architectural facade, ceiling and other decorative uses.

Welded grating is a made by forge welding of bearing bars automatically resistance-welded with the crossbars through application of intense heat and force. Forge welded steel bar gratings are most popular and versatile industrial grating types, available in a variety of materials, spans, bar thicknesses and loading capacities, particularly suitable as heavy duty gratings for static and dynamic loading in the form of walkways, safety barriers, drainage covers, platforms, ventilation grates and stair treads. Benefits of Welded Grating: By pressing and welding to form a homogenous unit of all intersection points, high shear forces can be absorbed. Depending on static or dynamic loading, heavy-duty gratings can be provided for many applications depending on the clear span. Material: Carbon Steel,Stainless Steel Surface: Smooth,Serrated Finish: Mill Finish, Black Primer, H.D. Galvanized Material Standard: Mild steel - We utilize a high quality mild steel for load bearing bars, which exceeds the strength of ASTM A36, BS4360 Grade 43A and JIS G3101 SS400, KSD3505 SB41. This is particularly beneficial where a floor is subjected to wheel loads, as deflection becomes a subordinate consideration to the ability of the load bearing bar to withstand high stress. Stainless Steel Floor can also be manufactured from stainless steel. The normal grade used are 304 and 316, but other grades can be considered upon request.

Steel bar grating is made up of bearing bar and cross bar as certain distance by welding or pressure locked. The combination of heavy-weight bearing bars and twisted steel cross bars provide excellent grating stability and loading capabilities. The cross bars are welded or electro-forged to the rectangular shaped bearing bars by a process that combines intense hydraulic pressure with a powerful electric current. Bearing bar types Flat type (also called plain type), serrated type, I bar type (I plain type and I serrated type).

The press-locked steel grating is a high strength grating made by pressing the cross-bar into the bearing flat steel or the pre-grooved bearing bar at each intersection to form the panels. Featuring light structure, high-performance, low-maintenance, Press-locked grating is used in civilian and commercial buildings, theatres, subway, suburban railway, and other municipal engineering, for handling pedestrian or vehicular loads. Common material types include Aluminum, Carbon Steel, Powder Coated Carbon Steel, Galvanized Steel and Stainless Steel. Popularly used materials include mild carbon steel and stainless steel. Press locked steel grating shows the same strength, long life and openness as welded grating. Serrated locked bar grating has an anti slippery extra safety surface. Spacing range can be custom designed to meet the requirements. This method of manufacture is particularly flexible that it allows for the production of grating with custom bearing bar spacing. Specify the following for your requirements: Height of End Plate (H); Pitch of Cross Bar (CP); Width of Grating (W); Length of Grating (L); Thickness of Bearing Bar (T); Pitch of Bar (PB); Height of Bearing Bar (H).

Galvanized Steel Platform Grating - Galv Grates for Operation Platform of Offshore Oil Rigs Galvanized steel grating with heavy zinc coating protection serves widely as strong, quick and durable bearing structural elements in offshore oil rig platforms, refineries, walkways, and many other industries. Steel gratings galvanized make an better choice over non-galvanized steel bar grating due to the fact that the galvanized coating helps protects the steel from corrosion. Platform Grating, is mostly made of heavy welded bar grating galvanised. Steel gratings serrated or grating panels combined with diamond pattern checker plate are safer and popular platform grating solutions.

Bar grating panels and perforated panels fabricated in sizes are popularly used as louver gratings for shade screening and air flow. Bar gratings for louvres are welded pressed grating constructed with transverse bars (louvers) pressed or lock into the bearing bars at an angle between 30 and 45. Qindelin louvre gratings work as shielding screen, ventilation grilles, facade cladding panels, fencings to stop people from peering through on bridges, gangways, elevated walkways,and other sites. It has four different louver blade angles. Varying degrees of shading and ventilating effects are achieved by angle changing of the cross bars pressed in, 15°, 30° or 45°. It is made of aluminum, stainless steel or carbon steel bright galvanized.
