We offer both adjustable and non-adjustable stainless-steel hooks to meet the needs of different customers.

Artsign offers various adjustable hooks, such as the AS-RH-12 model, to accommodate different tile thicknesses, rafter spacings, and roof unevenness. The adjustable mechanism avoids stress points on the tiles, reducing pressure and eliminating the need for forceful tile pressing to align with the guide rail.
This is very user-friendly for installers, reducing labor time; for contractors, it means lower labor costs; the adjustable hooks make it easier to straighten the guide rail, improving the homeowner's experience; and for suppliers/distributors, it reduces inventory pressure and lowers the risk of incorrect shipments.
In addition, we also offer fixed hooks. These fixed hooks feature a one-piece structure without adjustment holes or grooves, allowing for more direct stress over time, lower cost, and higher cost-effectiveness.

To meet the needs of different materials, we also offer stainless steel hooks made of aluminum. Aluminum roof hooks offer lighter weight, better system compatibility with aluminum rails, lower cost, and sufficient corrosion resistance for most residential PV installations.

These are all solar brackets for tile roof.
Artsign designs a wide variety of solar panel mounting system for metal roof. Such as aluminum roof brackets and N clips 
We offer two types of aluminum roof brackets: penetrating and non-penetrating. 
Penetrating roof brackets have high load-bearing capacity, suitable for strong winds and long spans.

N clips can be used with L feet and L connector to fix with long rail profiles. It can be directly work with solar mid clamp and end clamp and thus can fix the solar panels directly without any long rail. It’s light for transportation and easy for installation.

As we mentioned earlier, Artsign also designed solar brackets for slate roof. The straight stainless-steel hooks effectively solve the problem of secure installation without damaging the roof surface.

In addition to the solutions mentioned above, we also have a solution that is applicable to all three scenarios and is the most economical—an L Feet with a hanger bolt.

This is the most economical solution, requiring the fewest accessories. However, for tile or slate roofs, using hanger bolts damages the roof surface and may result in poor waterproofing.
