A great amount of time and trouble can be saved if the building parts are unloaded at the building
site according to a pre-arranged plan . Proper location and handling of components will eliminate
unnecessary handling .

Blocking under the columns and rafters protects the splice plates and the slab from damage
during the unloading process . It also facilitates the placing of slings or cables around the members
for later lifting and allows members to be bolted together into sub-assemblies while on the ground .
Extra care should always be exercised in the unloading operation to prevent injuries from handling
the steel and to prevent damage to materials and the concrete slab .

If water is allowed to remain for extended periods in bundles of primed parts such as girts,
purlins, etc ., the pigment will fade and the paint will gradually soften reducing its bond to the steel .
Therefore, upon receipt of a job, all bundles of primed parts should be stored at an angle to allow
any trapped water to drain away and permit air circulation for drying . Puddles of water should not
be allowed to collect and remain on columns or rafters for the same reason .

All primer should be touched up as required before erection .

noTe: Piece marks are stenciled on primary structural members.
