Hunan Haolv Building Materials Co., Ltd. is a 19 years experience source manufacturer offering durable and versatile enterprise-level Aluminium lean to glass roof systems for the construction industry. Our solutions are made from heavy-duty thermal break aluminium profiles with frame thicknesses ranging from 2.0–3.5mm and glass configurations from 6–32mm. We provide tempered, laminated and triple glazing choices.
Each system is ISO, CE and AAMA certified, and has multi-layer EPDM sealing and hidden drainage technology. We provide whole one-stop sourcing solutions via strategic alliances for consistent supply of raw materials and quick 25-30 day delivery cycles. Our systems are built to endure heavy wind, with the possibility of being reinforced for snow loads, making them perfect for residential villas, commercial terraces and garden rooms that need plenty of natural light and good thermal insulation.

Your construction projects need solid solutions that combine beauty with functionality. We provide product systems that are designed to suit any architectural arrangement – whether independent or connected to a wall. Energy savings is achieved without sacrificing the structure using thermal break aluminium technology.
The use of large glass brings natural light into your space, providing cosy atmospheres for patios, balconies and commercial leisure spaces. Large panes of glass are set in a strong aluminium frame, providing safety and visibility. UV-protected coatings and weather-resistant construction provide long-lasting value, engineered for decades of outdoor exposure.

Every project has different needs. We can provide extensive OEM/ODM customise according to your design or requirements. Our technical staff will work with you to choose the best kind of roof (glass, polycarbonate or insulated panels) for your climatic circumstances and performance objectives.
Surface coatings are available to suit aesthetic choices from slick powder coated colours to natural wood grain textures. Different opening mechanisms, such as sliding doors or folding configurations may be used to optimise the usefulness of the area. With our flexible design process, we may easily be incorporated to existing buildings and satisfy the load requirement of the project.

Multiple vendors complicate procurement and add to project risk. Our one-stop solution offers all the components needed – frames, glass, hardware and accessories – from a single verified supplier. It makes your supply chain leaner, minimises the coordination overhead and assures component compatibility.
We maintain strategic alliances with high-end suppliers such as CONCH to ensure stable quality of materials. Tight dimensional tolerances are maintained throughout our ISO-certified production procedures to ensure vital weather-tight installations. The quality control is strict, including tests for adhesion, film thickness, and uniformity of colour from batch to batch.
Each Aluminium lean to glass roof system is structurally validated against wind and snow loads appropriate to your location. Multi-layer EPDM sealing ensures no water enters and a hidden drainage system takes care of rainfall without visible disturbance.



You receive comprehensive technical consultation from inquiry through installation. Our experienced team provides application guidance, structural calculations, and system optimization recommendations tailored to your specific site conditions. Free samples are available to evaluate material quality firsthand (shipping costs apply).
With established inventory and mature supply chain management, we guarantee delivery within 25–30 days from order confirmation. This predictable timeline supports your project scheduling while our end-to-end follow-up ensures smooth execution. Our responsive communication addresses technical questions promptly, minimizing delays during critical construction phases.
Q: Can the aluminum frame support large glass panels without compromising stability?
A: Yes, our reinforced aluminum profiles are specifically engineered to support expansive glass panels. The heavy-duty 2.0–3.5mm frame thickness combined with optimized structural design provides exceptional load-bearing capacity while maintaining slim sightlines for unobstructed views.
Q: How does the thermal break technology improve energy efficiency?
A: The thermal break creates an insulating barrier within the aluminum profile, drastically reducing heat transfer between interior and exterior. This technology can lower U-values significantly, reducing heating and cooling costs while preventing condensation issues common in standard metal frames.
Q: What maintenance does a product require?
A: Minimal maintenance is required. The powder-coated or anodized finishes resist weathering and UV degradation. Periodic washing (annually or bi-annually) removes surface deposits. Unlike timber alternatives requiring regular treatment, your aluminum system maintains performance for 25+ years with basic care.
Q: Are these systems suitable for regions with heavy snow or high winds?
A: Absolutely. Our systems are designed with adjustable load specifications. We provide optional reinforcement for heavy snow regions and engineer wind resistance ratings based on your location's climate data. Each project receives structural validation ensuring code compliance and safety.
Q: Can I integrate opening windows or doors into the roof structure?
A: Yes, our systems accommodate various opening configurations including sliding doors, folding systems, and tilt-turn windows. This flexibility allows you to create ventilated spaces or seamless indoor-outdoor transitions according to your functional requirements.
