The rainy season for Tamil Nadu will begin soon. We have compiled a quick guide indicating ideal storage practices that will keep TMT rebars from deteriorating.
Storage Guidelines for TMT Rebars
Direct exposure of TMT rebars to water should be avoided. It is recommended that TMT rebars be stored in a covered yard. Covering with a tarpaulin sheet can be considered if a covered yard is not available. Before covering with tarpaulin, TMT rebars should be in dry condition.
Further, TMT rebars should not be kept on exposed soil. It is advised that TMT rebars are placed on a steel frame or wooden plates. For straight rebars, four support points are recommended and for bent rebars, two support points.
TMT rebars stored in a covered yard on a steel frame with adequate supports.
If there is no facility for keeping TMT rebars on a raised platform, they should always be placed on impermeable dry surfaces like cement flooring. However, this is not the best practice.
TMT rebars should be tied properly before loading or unloading to avoid accidents and to ease movement. Further, TMT rebars should always be placed in a straight line and not in zig-zag pattern.
Sometimes, especially during the monsoon season, surface of TMT rebars develop a reddish colour. This does not affect performance and such TMT rebars can be safely used for construction.
