1 Finished plates matched to the foundation

ZSJH supplies Custom Base Plates for Steel Building Columns as finished fabricated plates for industrial buildings, warehouses and extensions. Column footprint, anchor locations, leveling details and foundation drawings are coordinated before drilling or welding. Approved parts may include profiled edges, drilled or slotted holes, stiffeners and specified protective finish. Cutting-only blanks are a separately defined CNC service.

2 The dimensions that control fit

3 Match the hole pattern to the approved anchor layout

Anchor-bolt position and plate orientation must use a common datum with the foundation drawings. Hole clearance and slots are design requirements; enlarging a hole is not a routine substitute for correcting a mismatch. Provide the approved anchor layout and identify any as-built changes before plate manufacture. Anchor rods, nuts, washers, templates and grout are separate items unless listed in the quotation.

5 Fabrication and acceptance

Cutting and hole-making are selected for the thickness, edge quality and required tolerances. Confirm any drilled holes, machined bearing faces or bevels separately. Inspect overall size, thickness identification, hole pattern, flatness and edge condition. Where ribs or a column are welded, agree the WPS, welding code and weld inspection plan; AWS D1.1/D1.1M can be requested where appropriate. A loose unwelded plate does not require a fabricated-weld inspection package.

6 Surface condition and delivery

Confirm paint, galvanizing or uncoated delivery for subsequent welding. Mask or leave contact and weld areas as specified; do not assume every bearing surface is painted. For galvanizing, agree coating requirements and dimensional effects on holes. Batch labels connect finished plates to column marks and packing lists, with face protection where required.

7 Questions before ordering

Can a base plate use the building span as its size?
No; plate geometry and thickness follow the column reaction, anchor arrangement and engineered connection. Can material grades be exchanged?
Only with approval.
Can manufacturing start from a sketch?
The dimensions, tolerances and connection details must first be resolved and approved.

8 Request finished base plates from ZSJH

Send plate drawings/BOM, anchor layout, grade, thickness, hole and edge requirements, quantity, any welded attachments, inspection, finish and destination. ZSJH can assist with structural design and detailing if the connection information is incomplete.
