Usage/Applications of Steel Square Bar:
-The Square Steel is normally used as structure steel.
-Row material for other structure steel like steel angles, channels, I-beams, H-beams, etc…
Packaging & Delivery of Steel Square Bar:
-Packing Detail: The products can be packed in bundles by steel wires.
-Marks:
1, Tag marks: the tag marks will be tied up to each bundle of the products. The information is usually including supplier’s logo and name, product name, made in China, products’ specifications, the painted color and other information requested by customers.
2, Color marks: we will paint both ends of the bundles of these products to make sure that they are more evident. It’s will be more convenient for the customers to distinguish them at the destination port.
-Delivery Detail: 30~45 working days after receive buyer’s T.T. or L/C.
Transportation:
-The products can be delivered by bulk vessel or by container. As for container, products with the length of 6m will be loaded in 20’ container
