Tread plate
Checker plate with a raised rhombic or lentil pattern. Base-only calculated masses and verified GOST patterned masses are shown separately; ASTM and GB figures remain in verification.
- Base thickness
- 2.5 to 12 mm
- Width
- 600 to 2200 mm
- Length
- 1400 to 8000 mm
- Patterns
- Rhombic · lentil
The raised pattern has a weight of its own.
A 5 mm flat base calculates to 39.25 kg/m². GOST 8568-77 lists 41.8 kg/m² including its rhombic pattern—6.5% more.

Left: calculated flat base. Right: standard patterned mass. Pattern placement is schematic; base thickness is drawn to the same scale.
Sizes and weights by standard
Weights are theoretical, from nominal dimensions at 7.85 g/cm³: Actual delivered mass and billing basis must be confirmed with the quotation. Verified tables have been checked against the stated standard or catalogue source; Calculated values are nominal estimates, subject to the stated assumptions.
GOST 8568-77Base plate weight
Calculated
The base-only calculation excludes the ribs. Use the separate GOST patterned-weight table for nominal mass including the standard pattern.

| 3 | 23.5 | 0.6 |

GOST 8568-77Patterned weight per thickness
Verified
Theoretical weight including the raised pattern. Thickness is the base sheet thickness. The 6 mm rhombic value includes the December 2005 correction: 50.1 kg/m².

Theoretical and delivered weight
Multiply the nominal table weight by the ordered length or area to estimate theoretical mass. Delivered mass can vary with manufacturing tolerances. Confirm whether the quotation and invoice use theoretical or weighed mass.
Galvanised weight
Hot-dip galvanising coats every surface, so it adds more to light, thin sections than to heavy ones: roughly 1.5% on heavy plate, up to 8 to 10% on a light angle or thin tube. Compare galvanised to galvanised. Minimum coating per EN ISO 1461:
| Steel thickness | Mean coatingµm | Mean coatingg/m² per side |
|---|---|---|
| over 6 mm | 85 | 610 |
| 3 to 6 mm | 70 | 505 |
| 1.5 to 3 mm | 55 | 395 |
| under 1.5 mm | 45 | 325 |
