Gaoyi brand PVC roofing tiles are available in four colors—gray, brown, brick red, and dark green—and are suitable for residential and industrial buildings. PVC is highly weather-resistant and exhibits minimal color fading, making it ideal for projects that require a lasting appearance. When selecting a color, consider the color scheme of the surrounding buildings: gray or brown are good choices for off-white walls, while brick red works well with red brick walls; gray is recommended for large roofs, while dark green is suitable for small carports...

The price of Gaoyi resin roofing tiles fluctuates based on factors such as thickness, purchase volume, and shipping distance. Common thicknesses are 2.5 mm and 3.0 mm, with price ranges of 15–20 yuan and 20–28 yuan per square meter, respectively. Bulk purchases qualify for the 5%-10% discount, and long-distance shipping incurs an additional logistics fee of 2–4 yuan per square meter. Resin roofing tiles are lightweight, have low load-bearing requirements, and are corrosion-resistant, making them superior to color-coated steel...

Recently, prices in the PVC roofing tile market have stabilized due to raw material costs, falling by approximately 8%–10% compared to the same period last year, with some manufacturers offering volume discounts. However, distributors’ shipping cycles have lengthened to one week, and inventory is being cleared slowly. Distributors in southern China are lowering prices to clear inventory, thereby increasing the margin for profit concessions at the distribution level, which presents a favorable opportunity for procurement.

Resin roof tiles cost 25–40 yuan per square meter; including auxiliary materials and labor, the total comes to approximately 45–65 yuan. Thickness ranges from 2.5 to 3.5 millimeters; for pitched roofs, a thickness of 3.0 millimeters or more is recommended. Lower-priced products may contain recycled materials and are prone to color fading; when purchasing, pay close attention to samples, odor, and raw materials.

Under normal use, Gao Yi tiles have a service life of approximately 20–30 years, depending on climate and installation quality. They are UV-resistant and resistant to acids and alkalis; however, in coastal areas, their lifespan is reduced to approximately 20 years due to salt fog, while in temperate climates, they can last 25–30 years. Installation techniques are critical: proper handling of details such as overlaps, waterproofing, and fastening can extend their lifespan, whereas improper installation can have a significant negative impact.

The core of Gao Yi Resin Tile production consists of three stages: compounding, extrusion molding, and cooling and quality inspection, with all parameters documented and traceable. The raw material is primarily APVC, supplemented by stabilizers and other additives; imported and domestically produced materials are blended, with the formulation fine-tuned quarterly. During compounding, mixing time and temperature must be precisely controlled to prevent air bubbles and color variations; during extrusion molding, temperature differentials across the three sections and die clearances are strictly controlled to ensure uniformity.

When purchasing PVC roofing tiles, assess quality by checking that the cross-section is uniform and free of bubbles or discoloration, that the tiles feel heavy and have good resilience, and by verifying the certification information—such as the applicable standards, lot number, and date—imprinted on the back. Products without clear markings may be of questionable quality.

The production of resin roofing tiles requires a wide range of equipment; omitting any items will severely impact production capacity and quality. Equipment investment varies widely, ranging from approximately 300,000 to 400,000 for a small manual line to over 600,000 for a large automated line, depending on output and automation requirements. Quotes are prone to omissions, so it is essential to confirm details such as molds, auxiliary machinery, and electrical controls. Before establishing the plant, it is essential to organize the equipment list and configure it in the actual sequence of operations to ensure a clear understanding of the process.

The environmental philosophy behind resin roofing tiles centers on whether the production process is clean and hygienic and whether the product poses a health risk to humans. Qualified factories must achieve a high waste recycling rate, properly manage dust and volatile organic compounds (VOCs), and invest heavily in exhaust gas treatment. Regarding the products themselves, they must be odor-free and accompanied by third-party test reports verifying formaldehyde and lead content levels. The most effective way to determine whether a factory is environmentally friendly is to conduct an on-site inspection.

Although PVC-coated steel roofing accessories are small, they have a significant impact on the quality of roofing projects and are often overlooked, leading to rework. These accessories—including corner brackets, eave trim, and drip edges—are all essential for waterproofing, fastening, and drainage. Careful procurement is required before installation to ensure all components are present and to avoid safety hazards and installation defects.
