Rebar ends should be marked with a tag, which should indicate the specifications, steel grade, quantity, and material certificate number of the rebar.

When stored outdoors, the site should be level and elevated above the surrounding ground, with drainage ditches around the perimeter.

Stack the H-beams with the backside facing up or out to prevent snow and water accumulation. Ensure a height difference at both ends for better drainage.

Before installation, the construction unit shall conduct a special inspection of the product qualification certificates, design documents, and pre-assembly records of the components, and re-inspect and record the dimensions of the components.

5. Steel structures should utilize appropriate connection methods to ensure that the node design aligns with the simplified model used in structural calculations.

When lifting steel structures, appropriate measures should be taken to prevent excessive bending and deformation. The contact area between the rope and the components should be padded with blocks to prevent damage to the components.

7. After the steel structure is hoisted into position, it should be promptly secured with supports and other connecting components to ensure structural stability.

Workers engaged in高空作业 should place tools and spare parts in a tool bag; they must not throw them up and down.

When working in rainy conditions, reliable anti-slip measures must be implemented, and attention must be paid to lightning protection during the thunderstorm season.

Prior to construction, be sure to monitor weather conditions; operations are strictly prohibited in winds above grade 4.
