Use spreader bar or strong back with
multiple pick-up points to minimize sags.
For lifting, use nylon or padded slings; not
bare chains or cables.
Unload as close as possible to the point of
Concrete placement to minimize rehandling.
Store coated and uncoated steel separately.
Store bundles on suitable materials, such as
Space timber cribbing to minimize sagging.
Use nylon strapping or other non-abrasive
If outdoor storage is to exceed 30 days, cover
coated bars with suitable opaque material and
Shearing & Bending
Contact points on shearing and bending
equipment to be a suitable protective material.
Inspect bars after bending and repair any
Cracks with patching material.
Power shears or chop saw (avoid flame cutting).
Repair cut ends.
1. Remove coating from the areas to be welded.
2. Cleaned it with brush, remove any dust particles
3. Weld properly prepared area
-reinforcing steel should be welded according to the American Welding Society,
AWS D1.4/D1.4M Structural Welding Code – Reinforcing Steel.
-While in situ welding of epoxy coated bars adequate ventilation to dissipate fumes must be provided
-Tack welding is not permitted.
4. Clean all carbon deposits & slag from weld and HAZ
5. Apply patch up as usual practice.
– the damaged areas should be repaired using patch materials meeting ASTM A775/A775M.
Patch up Material
Use 2-part patching material, approved
by the coating manufacturer.
Follow manufacturer instructions.
Repair of damaged epoxy coating, cut ends,
cracks and abrasions
Remove rust and contaminants from the
damaged area to be patched with a wire
Mix the patching material according to the
manufacturer’s instructions. Use patching
material prior to end of pot life.
Apply the patching material to the repaired
area. Follow the patch material manufacturer’s
Allow the repaired area sufficient curing time,
as specified by the manufacturer’s instructions, before placing concrete.
Lift and set the steel into place without dragging.
Use plastic or bar supports coated with non-conductive material.
Use pvc coated tie wire.
Use power shears or chop saw to cut steel and not flame cutting.
Minimize traffic over the steel.
Avoid traffic and concrete hoses on placed steel.
Use plastic headed vibrators to consolidate concrete.
