Electro Forged Gratings - High-grade Steel, 25x3 To 40x5 Mm Sizes | Corrosion Resistant, Low Maintenance, Excellent Anti-skid Properties

Electro Forged Gratings -

Owing to our expertise in this domain, we are engaged in manufacturing and exporting a wide range of Electro Forged Gratings. Developed with utmost precision, these gratings are used in different sectors and are manufactured by making use of high-grade raw material like steel and basic components that is obtained from the accredited vendors of the industry. These gratings are known for their features like low maintenance, longer service life and corrosion resistant finish. The Electro Forged Gratings offered by us can be availed at industry leading prices.

Other Details -

• Electro Forged Gratings are produced by PLC controlled equipment which combines high hydraulic pressure (more than 100 Tonnes) and high electric current (Approx 2200 amps) to electro forge the cross bar and bearing bar into a single standard panel
• The elctro forging process eliminates any crack or open joint. The strength of bearing is also retained. The square twisted bar (cross bar) provides excellent anti-skid properties

Nomenclature of gratings + product Specifications -

The costs incurred in a project depend on these items mentioned below:

• Bearing Bar or Load bearing bar (BB)
• These bars support the load put on the grating and they are made from low carbon steel grade IS2062

Mesh

• It is the center to center distance between two adjacent bearing bars and cross bars

Cross Bar (CB)

• They are positioned transversely across bearing bars and are welded into them at their intersection points to provide lateral restraint
• In steel gratings these are made of square twisted wire rods from low carbon grade steel of SAE1008

Edge Binding or Frame Bar ()

• Bar fixed to the edge of gratings and flush with the top of bearing bars

Formed Binding Bar (FFB)

• Nosing: It is the member on the front side of the stair thread to improve skid resistance or avoid slipage

Kick Plate/Tow Plate

• A large flat bar welded to the end of the grating normally 100 mm above the top surface of the grating or as specified.

Carrier Plate

• 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 step

Span (L)

• Total length between the supports, ie the extreme ends of the bearing bars. It is measured parallel to the bearing bar. (Length of the load bearing bar)

Width (W)

• It is the overall width of the panel measuring 90o to the load bearing bar

Serrations

• Notches made on tip of the load bearing bar to improve skid resistance

Cut Outs

• The area of the gratings removed to allow structure, pipe, plant, obstruction or handrail to be fitted in

Product Specifications (All units in mm)

The following Load charts show the Safe Uniform loads for the corresponding Bearing Bar Size and span. The safe uniform loads have been calculated such that the elastic deflection shall not be more than 1/200 times the effective span or 10mm, whichever is lesser (Ref: BS4592).
