Their steel structures are exceptionally strong and precisely manufactured. The entire production process was highly professional.
Advanced Al-Zn alloy-coated steel substrates and ceramic-sintered granules are used in Luoyang Innovation Building Material Co., LTD's premium colorful roofing tile. These tiles, which are produced at our 50,000-square-meter production base, have a zinc layer of 30–275 g/m² sheet thickness of 0.2–0.6 mm and widths of 750–1250 mm. Our yearly production of more than two million square meters ensures a steady supply for big projects. With a lightweight profile of about 5.5–7.0 kg/m², our tiles attain tensile strengths beyond 350 MPa, greatly lowering the structural load requirements. Every production batch is guarantyd to meet strict quality requirements thanks to ISO 9001, SGS, and BV certifications.

A development in building envelope technology is represented by tile. It tackles important issues that architects and contractors around the world face.
Conventional clay tiles add undue structural weight. Metal sheets that are left untreated quickly lose their color. Regular replacement of standard asphalt shingles is necessary.
Our approach combines co-extrusion of ASA resin with Al-Zn alloy protection. This produces a roofing material that can tolerate temperature variations between -40°C and +80°C. Under intense sunlight, the coated surface withstands UV deterioration for more than thirty years.
Every panel has the same thickness thanks to the cold rolling processing method. Surface treatments produce a barrier that keeps moisture out. In industrial and coastal settings, galvanized coatings stop corrosion.
Our manufacturing process delivers precise dimensional control and consistent performance characteristics.

Outstanding thermal insulation is provided by the multi-layered composite structure. Both heating and cooling systems use less energy when there is little thermal conductivity.
According to ASTM G154, stone-coated versions pass the 2,000-hour accelerated aging test. In all climate zones, this guaranties long-term color stability.
Your building projects demand materials that perform under pressure. Our Colorful Roofing Tile deliver measurable benefits across critical performance metrics.
Structural Efficiency: The high strength-to-weight ratio eliminates the need for additional roof reinforcement. You save on structural steel costs while maintaining load-bearing capacity.
Corrosion Protection: Al-Zn coating mass of 150 g/m² provides superior anti-corrosive longevity. Salt-spray resistance testing per ISO 9227 confirms suitability for marine environments.
Acoustic Comfort: The textured surface acts as a natural sound buffer. Heavy rainfall produces minimal interior noise compared to smooth metal roofing.
Wind Resistance: Horizontal fastening systems withstand wind speeds up to 200 km/h. Interlocking designs prevent uplift during severe weather events.
Color Retention: Spectrophotometer testing ensures Delta E < 1.0 across production batches. Ceramic-sintered granules maintain aesthetic appeal for decades.

Before leaving our facility, each panel is put thru extensive testing. Critical parameters are continuously monitored by our sophisticated production system.
Tests for granule adhesion confirm weight loss of less than 0.2g each sample. By doing this, surface deterioration is avoided during installation and service life.
Tiles are submerged for 120 hours in boiling water resistance testing. We look for coating separation, blistering, and delamination.
The Class 4 UL 2218 hail test technique is followed by impact resistance. Samples are resistant to penetration and cracking under high-velocity impacts.
Precision micrometers are used in thickness verification to verify coating homogeneity. This ensures that corrosion protection is constant across production cycles.
Every batch is examined by our skilled technical staff in comparison to international quality standards, AISI, and ASTM. The most exacting building requirements are met by the materials you receive.

Your projects benefit from proven performance across demanding environments.
Coastal Residential Developments: High salt-spray resistance protects homes in maritime climates. Traditional metal roofs corrode within years; our tiles maintain integrity for decades.
Urban Retrofit Projects: Converting flat roofs to pitched designs becomes economically viable. The lightweight profile eliminates structural reinforcement requirements in existing buildings.
Industrial Facilities: Extreme climate resistance suits warehouses and manufacturing plants. Snow loads and high winds pose no threat to properly installed systems.
Commercial Buildings: Rich color options in red, blue, gray, and green enhance architectural appeal. Custom colors align with corporate branding and design specifications.
Specialized Construction: Cleanroom facilities and controlled environments benefit from the low particle emission profile. Smooth coated finishes prevent dust accumulation.
Vibrant red, professional blue, neutral gray, and natural green are examples of standard hues. To guaranty long-term color constancy, each shade is put thru UV stability testing.
Certain architectural needs are met by custom color matching services. Our design team works with you to achieve precise color specifications.
Large roof surfaces have a consistent appearance thanks to the coated finish. There are no discernible color differences across panels from various production batches.
Q: Will the color fade over time?
A: High-quality ceramic-sintered granules resist UV degradation through chemical bonding. You can expect color integrity for 30+ years under standard conditions.
Q: Is installation noisy during heavy rain?
A: The textured surface dampens sound significantly compared to smooth metal. Interior noise levels remain comfortable during storms.
Q: Can these tiles handle extreme heat?
A: Operating range from -40°C to +80°C accommodates desert and tropical climates. Low thermal expansion prevents warping during temperature fluctuations.
Q: How do they perform against wind uplift?
A: Horizontal fastening systems withstand hurricane-level winds exceeding 120 mph. Proper installation according to specifications ensures maximum resistance.
Q: Are these tiles environmentally friendly?
A: 100% recyclable materials reduce environmental impact. Lightweight construction lowers carbon emissions during transportation and installation.
