2. Use the T-bolts to attach the rail to the adjustable front support leg. Tighten the M8 hexagon screw securely.

3. Also In accordance with the planned array layout, place the adjustable rear support feet and legs in position using the EPDM waterproof gaskets between the foot and the roof material.Screw each foot through the roofing material into the purlins using the supplied wood screws taking care to place all feet in a straight line and in a matching position to the front support feet and legs.

4. Adjust the size of rear leg assembly by extending the central angle bar to the desired length. Use the supplied fixing nuts to secure the two sections in place.

8. Repeat steps until installation is completed.

A.Affordable price :with reasonable design,price of aluminum mounting system will not be very higher than C-steel mounting system (only about 25% price difference).

B.Save installation time and labor cost:Aluminum mounting structure has higher machining accuracy,much lighter weight,and part pre-assembly in factory,(save 30% installation time)

C.Save maintenance cost:with better anti-corrosion,aluminum mounting structure will have about 25 years duration lifetime,almost no need maintenance cost.But C-steel mounting will have to be repainted and re-welded to keep its service life.

D.High priced recycling:scrap aluminum can be sold in high price after using (about 40% purchase price of aluminum mounting),while C-steel will be valueless for years severe corroded.
