Define the actual checker sheet dimensions and material before selecting it for a staircase detail.

Grade and surface

Q235B in the title appears alongside SGCC, CGCC and DX51D-related parameters. Confirm one base material, diamond pattern and galvanized treatment rather than infer equivalence across the list.

Actual size labels

A 1250 mm specification is paired with four width ranges from 900 to 2000 mm. Clarify what the separate specification measures and select the actual thickness and length from the broader descriptions.

• Actual steel designation
• Thickness and pattern geometry
• Measured sheet width
• Length and edge requirements
• Zinc inspection criteria

Staircase acceptance

No friction, slip or support load result is supplied. Request material and coating records and the required application tests; anti slip wording and ASTM A653 references do not establish a tested staircase assembly.
