Product Description

Trusses can incorporate deep upper and lower chords, diagonal and vertical web members, reinforced gusset nodes, splice connections and lifting attachments. Fabrication planning considers member geometry, welding access, overall camber, trial assembly and transport segmentation.

Individual sections are cut and prepared using controlled templates and fixtures. Node assemblies receive particular attention because they transfer concentrated forces between chords and web members. Long trusses may be manufactured in match-marked transport sections and trial assembled to confirm alignment before coating and shipment.

Industrial workshops, aircraft hangars, stadiums, exhibition halls, transportation terminals, warehouses, power plants and large public buildings.

Drawing-Based Customization

Span, depth, member section, node geometry, splice position, camber, lifting points and coating are fabricated according to customer-approved drawings.

Manufacturing Process

Drawing review → member cutting → edge preparation → node and chord assembly → controlled welding → straightness/camber checks → trial assembly → NDT → coating → segmented packing.

CTA

Provide your truss drawings, span, loads and delivery limits for a project-specific fabrication assessment.
