Dense steel grating is welded steel grating that the spacing of bearing flat steel less than 25mm. It is mainly used in the occasion higher strength is needed for gratings. Material: High quality low carbon steel, stainless steel and alloy steel. Specification: The space of flat steel is 12mm or 20mm, the spacing of horizontal pole is 30mm or 50mm. Feature: In addition to having the advantage of special appearance form and easy installation, Dense steel gratings also meet the request of special occasion passing through. For example, dense steel grating is used for mild steel high-heeled shoes walk treading; for industrial and mining enterprises allowing objects flowing through. Application: Mainly used for ships, drilling platforms, offshore platforms, walkways, to secure walking and to prevent objects falling. Also used for factory aerial work platforms and high-level working platform by protecting the possible falling high-altitude litter.

Plug grating is a lightweight and durable flat steel structure widely used as building material in civilian and commercial buildings, theaters, metro, suburban railway and construction projects of various public works areas and facilities. The grating is made with carbon steel or stainless steel bars going through the opening (hole), plug, welding and finishing processes, galvanized or stainless steel natural color. Grating length The bearing grating length is the external grating dimension measured in the direction of the bearing rods (this applies even in the case that the grating length is shorter than the width thereof). Grating width The non-bearing grating width is the external grating dimension measured in the direction of the filling rods. Bearing rods The bearing rods are parallel grating chords supported on both ends and used to transmit the forces induced by the grating load. Filling rods The filling rods are chords sized as a rule to 10 x 2 mm maintaining the vertical position and stability of the bearing rods. Mesh size The mesh size is the axial distance between two adjacent bearing rods and two adjacent filling ones. Border band The border band is a steel band used as a border and reinforcement of the peripheral grating area; as a rule, the cross-sectional area of the border band is identical with that of the bearing rod of the grating. Unidirectional Anti-Slip Arrangement Indentations cut out in filling rods creating an effective anti-slip grating arrangement. Bearing structure Supporting structure, as a rule steel or concrete construction, where gratings are anchored. Cut outs Rectangular, oblique and/or bow-shaped apertures in grating structures cut out in accordance with the Customer drawing or sketch. Step sides Staircase step sides made from flat bars and used to screw the step onto the staircase bearing structure (the string boards). Feature: Plug steel grating has lightweight, high strength, corrosion- resistance, it is strong, durable, maintenance-free, beautiful and a great choice for use in both residential and industrial applications.

Light duty grating panel is made of open mesh welded construction which gives the panel a light structure for easy carrying and installation. At the same time, the light structure does not allow heavy bearing load. This light style open grid grating provides maximum passage for light, air circulation and drainage, making ideal and economical solution for celling in factory or industrial workshops. Materials and Structures: Light duty bar gratings are manufactured from low carbon steel, stainless steel or aluminum steel. It is joined at the intersection of the bearing bars and cross bars. Light duty bar grating ranges in size from 3/4" x 3/16" to 2 1/2" x 3/16". Uses: Light duty grating panels can find applications in roof safety, conveyor system, operating plants, highways and bridge platforms and walkways, machinery floors, refineries, tank stairways and power plants. Stainless steel light duty grating is also available for specific applications. The finish can be galvanized or manufacturer's standard black paint at the discretion of the architect. It can also be painted by request. Manufacturing tolerances: Cross bar alignment and spacing Cross bar shall not vary more than 1/8" in 12" either direction from perpendicular alignment with bearing bars. Overall dimensions and placing: Width is overall lengths of cross bars at opposite ends of panels.

Heavy duty steel gratings are economical flooring solutions having excellent load capability and a slip-resistance surface. The Heavy Duty style grating sheet handles a heavier load than other steel grating, with added angle noising, it provides additional support along the back edge of the tread to provide superior strength.

Compound steel grating is a product made of steel grating with certain crossing style and checkered plate surface in different thicknesses. The grating type JG323/40/100, JG253/30/100 and JG323/60/100 are generally used as base support materials. The checkered steel plate galvanized or hot dipped with 3mm thickness is used as surface plate. Checkered plate is used as surface tread plates with a thickness of 4mm, 5mm or 6mm according to customers’ requirements. Compound steel grating will generate buckling deformation due to thermal stress after hot dip galvanizing, and larger steel grating has difficult levelling due to the fact the panels are two layers of metal sheets combined firmly together.
