Base Plate Reference Data
Base plates provide the bearing surface between steel columns and concrete foundations. The configurations below are standard arrangements per BS EN 1993-1-8 and typical UK practice. Actual base plate sizing, thickness, and bolt layout must be confirmed by a structural engineer based on the specific loading and foundation design.
Standard Configurations (BS EN 1993-1-8)
| Column Serial Size | Typical Plate Size (mm) | Common Thicknesses (mm) | HD Bolt Pattern | HD Bolts |

Grout Thickness Guidance
Grout provides a level bearing surface and accommodates minor foundation irregularities.
| Standard Grout Thickness | 50–75 mm |
| Maximum Thickness | 100 mm (requires structural design) |
| Grout Specification | Non-shrink cement-based grout, min. 40 MPa strength |
| Surface Preparation | Foundation must be level; base plate levelled with shims before grouting |
| Curing Time | Min. 7 days before applying load (check grout datasheet) |
