Steel Structure Connection Components

Steel structure connection components include plates, cleats, brackets, splice parts, anchor assemblies and project bolts fabricated and supplied to approved connection details, grades, hole classes, coatings and traceability.

02Product form

Specifications and dimensions

  • Approved member geometry, fabrication tolerances, hole classes, camber and component identification
  • Shop assemblies or transport segments matched to shipping, lifting and erection constraints
  • Surface preparation, coating system, dry-film thickness, fire protection and repair procedure

Standards and supply condition

  • Project structural design and execution standards with approved drawings govern the finished system
  • ISO 3834 quality requirements or the specified equivalent govern fusion-welding quality management

Manufacturing and processing

  • Purchased plate and sections are identified, cut, drilled, formed and assembled under controlled drawings and material traceability.
  • Qualified welding, dimensional inspection, NDE, surface preparation, coating, marking and sequenced packing complete fabrication.

Typical applications

  • Bolted frame and bracing connections
  • Base plates, anchors and embedded parts
  • Equipment, facade and secondary-steel interfaces

Quality and acceptance controls

  • Control approved drawings, revision status, material traceability and component identification through fabrication.
  • Review WPS/PQR, welder qualifications, weld inspection, NDE acceptance and dimensional inspection records.
  • Inspect bolt holes, trial assembly where required, coating preparation and thickness, packing marks and erection sequence.

Include in your RFQ

  • Project location, governing design code, use and design-life basis
  • Approved geometry, grid, elevations, loads and interface drawings
  • Material grades, product standards, connection and bolt requirements
  • Fabrication standard, welding quality level, NDE and inspection plan
  • Corrosion category, surface preparation, coating and fire protection
  • Supply boundary, erection responsibility, packing sequence, destination and schedule

Selection limits

  • Supply content does not include licensed structural design for the buyer's jurisdiction unless expressly contracted through qualified parties.
  • Final member sizes, connections, fire protection and erection stability must follow approved project engineering, not catalogue examples.
