Grade Thickness Width x Length; AA3105 & 5052 Checkered/Tread Plate (5 Bars Pattern) 3.0mm to 8mm: 1220mm x 2440mm (4 Ft. x 8 Ft.) 1220mm x 3658mm (4 Ft. x 12 Ft.) Plate thickness: 5–50 mm b. Specifications ASTM A-786, medium 4-way pattern, commercial grade mill finish, not polished Chequered Plate, also known as Steel Floor Plate or Steel Tread Plate has a raised diamond lug pattern that provides excellent skid resistance for a wide range of applications. Thanks in advance. Pattern to ASTM A786, Pattern 4. Steel Checker Plate Information: Manufactured in accordance with BS EN 10025-2 : 2004. This guide introduces measurement principles and provides an easy-to-understand explanation of the instruments and methods needed to … AR235 / AR200 / AR Medium; AR400F; AR450F; AR500F; AR400 Flat Bars; ASTM A514; ASTM A829 AISI 4130/AISI 4140; Marine & Offshore Steel Plate. 1. The method of aluminum checker plate thickness measurement is as follows. Other designs include diamond plate. Steel Plate. I try also to make the distances of the stiffener as close as possible but it still fail. In addition to the cleanliness of the surface of the patterned aluminum plate, we need to see more things. Chequer Plate Direct specialise in ‘5 Bar Tread’ which is a pattern consisting of 5 raised bars arranged in an alternating pattern. Checkered steel plates are measured and represented by plate thickness, and thickness … chequered surface in which case the thickness of the base plate shall be taken for the calculation or cross-sectional area. ASTM A131 A&B / ABS A&B; ASTM A131 / ABS AH36 / ABS DH36 / ABS EH36; API 2H Grade 50; ASTM A633; PVQ Steel Plate. 3.0 1000 1250 Can anyone recommend how to design this checkered plate? Checker plate, tread plate or durbar floor plate is the term given to sheet metal that has distinctive raised marks on the surface. 2) The thickness of the oxide film. 8.1.2 Number of samples for tensile test shall be in accordance with IS 2062.
