Product Description
Flat roof mounting solution without roof penetration. It is fixed by concrete ballast blocks, fully preserving the roof waterproof structure. Simple and fast installation with zero damage to the original building structure, suitable for various industrial and commercial concrete flat roofs.

FAQ
Q1: How much ballast weight is needed per ㎡?
A1: Calculated from project wind pressure: 80–120 kg/㎡ for 40–42 m/s; for 50 m/s, 150–200 kg/㎡ or mechanical anchoring is required. Professional ballast calculation reports available.
Q2: Will it be blown away by strong wind?
A2: Aerodynamic design + sufficient concrete ballast; the ballast schedule above covers 40–42 m/s, higher wind speeds require the reinforced scheme described.
Q3: Will ballast damage roof waterproofing?
A3: Rubber pads under ballast blocks evenly disperse pressure and avoid direct wear on the waterproof layer.
Q4: Is it suitable for high-rise buildings?
A4: Most recommended for low/mid-rise industrial & commercial buildings; penetration solutions are better for super high-rises.
