Advantage
▶ Selection calculation:
Based on the actual loads (static load, dynamic load, wind load, snow load) and support spacing, have the structural engineer review the bearing capacity of the section.
▶ Coating protection after cutting:
If you choose to purchse long profile of main structural member and cut on site. After such on-site cutting or drilling, the cut surface should be applied with zinc-rich repair paint to prevent rust from spreading from the surface.
▶ Connection fitting:
Only use the special connecting pieces from Solar First that match the U steel.
▶ Installation torque:
The tightening torque of the bolts must be carried out in accordance with Solar First design requirements. If it is too tight, it may cause edge curling deformation; if it is too loose, it will not have sufficient anti-slip ability.

Important Notes:
▶ Selection calculation:
Please, based on the actual loads (static load, dynamic load, wind load, snow load) and support spacing, have the structural engineer review the bearing capacity of the section. Do not blindly select based on experience.
▶ Galvanizing layer protection:
After on-site cutting or drilling, the cut surface should be coated with zinc-rich repair paint to prevent rust from spreading from the surface.
▶ Connection fitting:
Only use the special connecting pieces that perfectly match the inner rolled edge shape. Ordinary angle iron clips cannot securely lock and are prone to loosening.
▶ Installation torque:
The tightening torque of the bolts must be carried out in accordance with the design requirements. If it is too tight, it may cause edge curling deformation; if it is too loose, it will not have sufficient anti-slip ability.
▶ Storage protection:
During transportation and storage, avoid deformation caused by heavy objects pressing on it; for long-term outdoor storage, elevate it to prevent moisture and protect against damage to the galvanized coating.
▶ Welding restrictions:
If welding is indeed necessary, low-hydrogen welding rods should be selected, and the heat input should be controlled. After welding, reapply anti-corrosion treatment - full bolt connection is highly recommended.
Summary
The U steel solar mounting structure integrates high load-bearing capacity, excellent torsional resistance, convenient installation, and long-term weather resistance. The slot holes on steel profile and no welding design, this product could be installed quickly.
