M.S(M&S) steel grating production method: According to the specifications provided by the customer, processing, welding, cutting and final packaging, if there is a corner, the corner must be removed first. As shown below Steel Bar Grating type: According to the manufactureing process, steel grating can be divided into Pressed Welded Steel Grating and Plug The Steel Grating. According to the shape of the load-bearing flat steel, it can be divided into I Type Steel Grating, Serrated Steel Grating and flat steel grating. Bar Grating fixing method: Steel Bar Grating can be fixed by welding and Steel Grating Mounting Clip. The advantage of welding is that it is permanently fixed and will not be loose. The specific position is on the first side of each corner of the steel grating. The length of the weld is not less than 20mm and the height is not less than 3mm fillet weld. The advantage of the Steel Grating Mounting Clip is that it doesn't damage the hot-dip galvanized layer and is easy to disassemble. At least 4 sets of mounting clips are required for each board. The number of mounting clips increases with the length of the board. The safest method is to use the lower clip directly. The screw head is welded to the steel beam to ensure that the steel grating does not slip off the beam due to the looseness of the mounting bracket.

How to Express Steel Grating Dimensions Do you know the specifications of G323/50/100FG, 19-W-4 and WA303A/1? Now let's analyze it one by one. 1. G323/50/100FG (Unit: mm) 2. WA303A/1 (Unit: mm) A--steel grating cross bar pitches is 100mm ( It could also be B, meaning the pitches is 50mm) 303--the height of the bearing bar is 30mm and the thickness is 3mm. 1--steel grating bearing bar pitches is 30mm(It can also be 2, indicating that the pitches is 40mm. It can also be 3, indicating that the pitches is 60mm.) 3. 19-W-4 (Unit: '') 19--bearing bars spaced at 1 3/16" on center 4--cross bars spaced at 4" on center

As the picture shows, when the bearing bar is larger than 5mm, the average zinc layer is greater than 610g/m2. when the bearing bar is less than 5mm, the average zinc layer is greater than 460g/m2. It should be noted that before galvanizing, the flat steel needs to be pickled to enhance the adhesion, so the thickness of the flat steel is not increased after galvanizing. This cannot be used as a standard for steel gratings. The amount of zinc directly affects the service life of the steel grating, which is also a concern of users. The quality and requirements after galvanizing must comply with the provisions of GB/T13912, bar grating can also be produced according to ASTM (A123) or BS 729.

If you are looking for a product that will allow ventilation, drainage, or perhaps decorative , your have three main choices: Expanded Sheet Metal, Perforated Sheet Metal, or Welded/Woven Wire Mesh. So which one do you choose and why? There are three main differences: Manufacturing Process, Characteristics, Typical end uses. Manufacturing Process: Expanded metal sheet Expanded metal sheet is made by first creating multiple slits in the sheet, and then stretching the sheet. The stretching creates a unique diamond pattern opening with one of the strands protruding at a slight angle. These raised strands can be flattened later in the process if desired. As you can see this process creates no waste (thus keeping down production costs) and it can add structural strength to the product. Perforated metal sheet Perforated metal sheet is a product that is made from sheet steel that has been fed through a machine that punches out round holes (or other designs). These holes can be straight rows or staggered to increase the amount of the openings. Typically the perimeter of the sheet has a boundary where holes are not punched; this adds stability to the sheet. The removed metal from the holes can be recycled but it also increases the cost of the product. The larger the hole size (or increased amount of holes), the greater scrap volume, and therefore costs can be increased. Wire mesh (welded) Welded wire mesh is a metal wire screen that is made from various alloys including steel, stainless steel, brass and copper. It is available in various sizes and shapes. Grids of parallel longitudinal wires are welded to cross wires at the required spacing, using electric fusion. The machines that are used to produce the mesh have precise dimensional control. Wire mesh (woven) Also available in steel, stainless steel, brass and copper, woven wire mesh is made as a cloth with wire threads woven at right angles. Wires which run lengthwise are known as warp wires, whilst those running perpendicular are weft wires.There are two common styles of weave: plain weave and twill weave. It can be made from various alloys including stainless steel, brass and copper. Wire cloth can be woven to create a variety of opening sizes and wire diameters. Characteristics: Expanded metal sheet One of the benefits from the manufacturing of expanded metal is that the sheet retains its structural integrity because it has not undergone the stress of having shapes punched in it (like perforated sheet), and the mesh-like pattern will not unravel (like woven mesh can do). Expanded metal has been stretched rather than punched, reducing scrap metal waste; making it cost-effective. The main considerations when using expanded metal will be the chosen thickness and strand dimensions (weight and structural design requirements). Expanded metal can be almost transparent (depending on the opening); it has mechanical properties and is an excellent conductor. Perforated metal sheet Perforated metal sheet comes in a virtually endless variety of sizes, gauges, hole shapes and material types. Hole diameters range from a few thousandths of an inch to more than 3 inches, punched in material as thin as foil or as thick as 1-inch steel plate. From lightweight decorative elements to load-bearing structural components, perforated metal offers unique opportunities to combine strength, functionality and beauty. Wire mesh (welded) The chance of improper bending of bars is reduced since bending machines bend the mat as a single unit. This provides the exact size of reinforcement where needed through variable bar size and spacing, thereby reduces steel waste. There can be a considerate savings because mesh is easy to handle and can be installed much faster. Typically you can purchase a welded mesh for less than a woven mesh. Wire mesh (woven) Wire mesh is adaptable to almost any application. It is extremely durable and very easily cleaned. Typical end uses: Expanded metal sheet Expanded metal sheet works well for steps, flooring in factories and on construction rigging, fences, wash stations, and security applications. Perforated metal sheet Perforated metal can be made into a multitude of products such as: screens, filters, baskets, trash cans, tubing, light fixtures, vents, audio speaker covers and patio furniture. Wire mesh (welded) Widely used in agricultural applications, industrial, transportation, horticultural and food procuring sectors. It is also used in mines, gardening, machine protection and other decorations. Wire mesh (woven) From sifting and screening machinery to conveyor and automotive belts, all the way to animal enclosures and architectural framework.

Nowadays, steel gratings are used in construction projects, and their superiority is also well known by many people. However, when buying steel gratings, what problems should be paid attention to? The detection method that will be used. When purchasing steel gratings, pay attention to the shape and flatness of the steel gratings. If the steel gratings are purchased in large quantities at one time, avoid taking care of the flowers and weeding one by one. It is found that the steel gratings are flat or the shape is not beautiful enough. Requires exchange, do not underestimate the shape of the steel grating, the steel grating with good quality and no obvious holes in the welding points is a qualified steel grating. It is necessary to pay attention to the inspection of the size of the steel grating. It is necessary to specifically measure whether the size of the steel grating meets the specifications and whether the dimensions are deviated. The steel grating should meet the standards required by the standard and the supply contract. The performance check of the steel grating is also required. Manufacturers should regularly take samples for load performance testing of products, and should also provide testing, test reports and quality certificates according to user requirements. Check the packaging of Chengdu steel grating. Generally speaking, the steel gratings are packed with steel strips when they are shipped from the factory, and the weight of each bundle meets the requirements of the customers. After the factory and the parties agree on the specifications, the supplier will pack according to the requirements of the customers. Also check the packaging mark of the steel grating. The packaging mark shall indicate the code of the trademark or the manufacturer, the model number of the steel grating and the standard number. Each steel grating shall be marked with a number. The quality certificate of the product shall indicate the steel grade, model specification and standard of the steel grating product. No., surface treatment, appearance and performance inspection results, weight per batch, etc. In addition to these, the quality certificate should be delivered to the customer as a basis for acceptance of the steel grating with the same batch of product. In consideration of the safety of the customer and the construction of the building, the manufacturer can also be required to provide a quality assurance certificate for the raw materials to ensure the quality of the steel grating.

Common Bar Grating Terms: Bearing Bars: Load-carrying bars made from steel strip or slit sheet or from rolled or extruded aluminum and extending in the direction of the grating span. Bearing Bar Centers: The distance center to center of the bearing bars. Carriers: Flats or angles which are welded to the grating panel and nosing of a stair tread and are bolted to a stair stringer to support the tread. Clear Opening: The distance between faces of bearing bars in a rectangular bar grating, or between a bent connecting bar and a bearing bar in a riveted grating. Cross Bars: The connecting bars made from steel strip, slit sheet, or rolled bars, or from rolled or extruded aluminum, which extend across the bearing bars, usually perpendicular to them. They may be bent into a corrugated or sinuous pattern and, where they intersect the bearing bars, are welded, forged or mechanically locked to them. Cross Bar Centers: The distance center to center of the cross bars. Curved Cut: A cutout following a curved pattern. Cutout: An area of bar grating removed to clear an obstruction or to permit pipes, ducts, columns, etc. to pass through the grating.

Span of Bar Grating: The distance between points of grating support, or the direction of this dimension. Also referred to as length. Straight Cut: That portion of the cut edge or cutout of a grating which follows a straight line. Swaging: A method of altering the cross-sectional shape of a metal bar by pressure applied through dies. Toeplate: A flat bar attached against the outer edge of bar grating or rear edge of a tread, and projecting above the top surface of grating or tread to form a lip or curb. Bar Grating Stair Tread: A panel of bar grating having carriers and nosing attached by welding, and designed specifically to serve as a stair tread. Trim Band: A band which carries no load, but is used chiefly to improve appearance. Welded Bar Grating: Bar grating in which the bearing bars and cross bars are joined at their intersections by a weld. Width: The overall dimension of a grating panel, measured perpendicular to the bearing bars, and in the same direction as the cross bars.
