W30 Series Wide Flange Steel Beam Packaging and Transportation Instructions:
1. Before leaving the factory, the steel beams are sorted by specifications in batches to prevent mutual collision and deformation during transportation.
2.Long-length steel beams are fully covered with high-strength waterproof tarpaulins to prevent rain, moisture, and rust caused by sea transportation.
3.During packaging, special attention is paid to protecting the flange edges and ends to minimize the impact of scratches and bumps on the overall dimensions.
4.Special lifting tools are used in conjunction with forklifts for lifting and handling to ensure a smooth and safe loading and unloading process.
5.After being loaded into containers or frame cabinets, reinforcement and fixation are carried out to prevent sliding, tilting, and damage during transportation.
6.It is suitable for various logistics methods such as road transportation, sea export, etc., and can be delivered in batches according to the project delivery schedule.
1. What is the maximum length that the W30 series wide-flange steel beams can reach?
Answer: The standard factory length can reach 12 meters. For extra-long pieces, they can be transported in frame cases or processed section by section according to transportation restrictions.
2. Where does the W30 steel beam have an advantage compared to ordinary H-shaped steel?
Answer: The flange is wider, the section moment of inertia is greater, and under the same load, the lateral stability is better, making it more suitable for large-span and high-rise load-bearing structures.
3. What is the minimum order quantity for purchasing W30 steel beams?
Answer: There is no mandatory minimum order quantity for the available specifications. Small sample orders, project replenishment orders, etc., can all be accepted; custom processing orders will have a minimum processing quantity set.
4. What thickness can the W30 steel beam achieve after hot-dip galvanizing?
Answer: The thickness of the galvanized layer can be controlled according to the customer's standards. Generally, it is above 85 μm, which can effectively enhance the corrosion resistance of the steel in humid and coastal environments.
5. Will the W30 steel beams have problems of being too high or too wide when loaded into containers?
Answer: We will calculate and arrange the layout in advance. Standard specifications can be normally loaded into standard containers; for the extra-wide and extra-long models, the frame case solution will be adopted.
6. After receiving the goods, how can we quickly verify the material of the W30 steel beams?
Answer: You can compare with the material list provided with the goods to check the furnace number, or you can entrust a third-party institution to take samples for reinspection and test the mechanical properties and chemical composition.
