Galvanized Steel Chequered Floor Plate


Diamond Checkered Tread Plate Galvanized Finish for Steamer Floor Construction


Checkered Plates are mainly for processing of anti-skidding, anti-slippery metal floor plates. 

Sloting: Slotted Metals are mainly used for making of slotted liners or pipes. Processing needed for wide metal sheet so that mechanical stress will be reduced. It will improve yield, but reduce metal sheet resistance, hence increase voltage drop along the metal tube. The metal slot procedure is for metal Stress Relief, is for releasing stress in every wide metal line. Also slot directions in metal should be parallel in current flow not perpendicular. Slotted metal sheets are made into channels or pipe well screens.


Embossed Metal Sheets are mainly applied for decorative designs of metal jewelries and crafts. The sheet metals or non-metal materials are produced with raised or sunken designs or relief by means of matched male and female roller dies, theoretically with no change in metal thickness, or by passing sheet or a strip of metal between rolls of the desired pattern.


Metal sheet is drawn through the male and female roller dies producing a pattern or design on the metal sheet. Depending on the roller dies used, different patterns can be produced on the embossed metal sheet.


Mild Steel Checker Plate makes ideal anti-slipping material where a large area flooring needs to be covered. Manufactured from one-piece sheet material with serrated edges on top, the chequered diamond plates provides an anti-slip resistant grip from all directions. Checkered plates are used as the floor panels or wall panels. Also written as Chequered Plate or Checkered Plate. The steel tread plates with raised chequered patterns will prevent floor or surface from being damaged due to movement of goods, for example, pallet trucks in a warehouse environment and the interior of a truck/van, ship flooring, decks, oil field drilling station tread plates. Steel checker plates are mostly finished with hot dipped galvanizing layer or zinc plate to achieve enhanced anti-corrosion resistance property and bright silver surface. The plated carbon steel checker plates are used also with bar grating as covering surface to form a stair tread with light weight and strong structure.


We also supply aluminum checkered plate for your choice. Galvanized steel checker plates cost less compared with aluminum plate. Aluminum floor plate has less weight and will never get rust. We encourage customers to choose according to specific uses.


Features and Application: Chequer plate (checker plate) is both slip-resistant and decorative. We can supply perforated draining cover plates, fabricated step plates or tread plates.


Standard Sheet Thickness:2-30MM

Plate Width:1000mm-3000 mm

Sheet Length:1000mm-18000mm as customer demand

Application: Perforated checker plates are used in Ship building, Engineering construction, Mechanical manufacturing. 

Patterns:Diamond,Hyacinth Bean, Chrysanthemum or according to your requests.
