After the fabrication of steel structural components is finished, check their dimensions and shapes complying with design drawings and relevant standards and specifications. Components with fabrication deviations within allowable ranges shall be derusted and painted as required by the design.
Qualified steel components shall be properly packaged and tagged with information such as quantity, project number and destination, to facilitate loading, transportation and on-site storage.
Small parts and accessories (generally mounting bolts, washers, connection plates, joint angles and other parts under 25 kg) shall be cased or bundled with a packing list provided. Each case shall be clearly marked with case number, gross weight, net weight, component name and part number.
Wooden cases must be sturdy and rainproof. The bottom shall be fitted with load-bearing sleepers with forklift access holes. Both ends of the sleepers shall be chamfered for easy hoisting and binding. The weight of each wooden case shall not exceed 1 ton in general.
Steel cases are mainly used for long-distance transportation to external projects. Welded steel cases are solid and durable. On construction sites, the case plates can be used as mounting shims or temporary fixtures. Lifting lugs shall be welded on steel cases.
Bundling is suitable for slender components for short-distance transport, such as grid members and roof truss tension rods. Do not make each bundle too heavy. Lifting appliances shall not be directly fastened to binding wires.
If components are to be installed right after fabrication, small parts and accessories may be firmly bundled or bolted onto corresponding positions of the main structure instead of being cased. The fixing shall not affect transportation and installation.
Packaging can only be conducted after the paint coating is fully dry. The packaging shall protect the coating from damage, and ensure all components and parts free from deformation, damage and loss.
