Overview

The thermo metal roof tile combines a waterproof locking profile with a rigid PU insulation core: a 0.4mm aluminum-zinc coated steel face with fluorocarbon coating, PU foam core and aluminum-foil backing. It offers high strength, good insulation and lightweight handling for pitched roofs.

Clip-and-lock concealed fastening means no exposed nails, making installation fast and weather-tight. It suits self-built houses, workshops, guesthouses and landscape buildings, and is a practical choice for flat-to-pitched renovation.

Typical Applications

  • Self-built house and guesthouse roofs
  • Factory and warehouse roofs
  • Landscape building roofs
  • Flat-to-pitched renovation of old buildings

Installation Notes

  • Recommended roof slope: 15° or more
  • In coastal high wind-pressure areas, increase the number of fixings to the purlins and strengthen eaves wind resistance
  • For re-roofing over existing color-coated steel, the new tile can be installed directly on the purlins without removing the old sheet

FAQ

How long do thermo metal roof tiles last? Will they rust?

The face is aluminum-zinc coated steel with a fluorocarbon coating, offering good corrosion resistance. Under normal conditions the tile is expected to last 30-50 years, depending on local climate (coastal salt spray or industrial environments). Regular roof drainage checks are recommended.

Can they be used to retrofit an old flat roof (平改坡)?

Yes. The tile is lightweight, adding little load to old structures, and installs with a clip-and-lock system without breaking the existing roof structure — a common solution for flat-to-pitched renovation projects.

How good is the insulation?

The rigid PU core has a low thermal conductivity, insulating better than ordinary color-coated steel sheeting: it reduces heat loss in winter and blocks solar heat gain in summer, lowering air-conditioning energy use.

Are they suitable for coastal areas?

The aluminum-zinc coated steel face has good salt-spray resistance. The clip-and-lock installation gives good overall integrity and wind-uplift resistance. For high wind-pressure coastal projects, extra fixings are recommended — please discuss the node design with our engineers.
