Product Introduction

This product is made using ABA co-extrusion technology. The A layer is made of corrosion-resistant and weather-resistant modified PVC material, and the B layer is made of light-shielding, rigidity-enhancing, and heat-insulating modified PVC material. It is an upgraded product of the traditional single-layer PVC corrugated sheet.

Installation Instructions

1. For corrugated sheets with thickness ≤1.3mm, the recommended purlin span for sloped roofs is ≤600mm, and for arched roofs, it is ≤800mm;

2. For corrugated sheets with thickness 1.8mm≥thickness>1.3mm, the recommended purlin span for sloped roofs is ≤800mm, and for arched roofs, it is ≤900mm;

3. For corrugated sheets with thickness 3.0mm≥thickness>1.8mm, the recommended purlin span for sloped roofs is ≤900mm, and for arched roofs, it is ≤1000mm;

4. Medium wave, small wave, and small trapezoidal wave must overlap 2 waves horizontally, and the longitudinal overlap length must be >300mm;

5. If self-tapping screws are used for fixing, pre-drilling is required. The diameter of the drilled hole must be 2-3mm larger than the diameter of the fixing screw. The diameter of the self-tapping screw must be greater than 6.0MM, and the thicker the tile, the higher the requirement for the self-tapping screw (it is recommended to use a dedicated "self-expanding screw" for fixing).

Note: The purlin span is related to the temperature of the workshop. If the temperature of the workshop is higher, the purlin span design should be smaller, otherwise it is easy to cause tile deformation.

Product Parameters

Thickness: 1.5mm, 2.0mm, 2.5mm, 3.0mm

Color: White, Blue, Green

Panel Type: T1050, Z1120

Product Features

Corrosion Resistance:No chemical reaction or discoloration after being soaked in salt, alkali, and various acids below 60% for 24 hours. It is very suitable for areas with frequent acid rain, corrosive plants, and coastal areas, with particularly significant effects! (Note: Low-quality products will severely discolor after being soaked in acid!)

Weather Resistance:The surface material is made of co-extruded weather-resistant resin, and the surface weather-resistant layer thickness is ≥0.2mm, ensuring product durability and corrosion resistance.

Sound Insulation Performance:Tests have shown that when exposed to external noise from rainstorms and strong winds, Hongbo APVC anti-corrosion composite corrugated tiles have a good noise absorption effect, with noise reduction exceeding 30dB compared to color steel plates.

Heat Insulation and Thermal Insulation:The thermal conductivity of this product is 0.325w/m.k, approximately 1/310 that of clay tiles, 1/5 that of cement tiles, and 1/2000 that of 0.5mm thick color steel tiles. At the same time, it is completely light-shielding. Compared with two-layer co-extrusion, the biggest advantage of this product is that it significantly improves heat insulation performance.

Impact Resistance and Low Temperature Resistance:This product has strong external impact resistance. Experiments show that a 1kg steel ball dropped freely from a height of 3 meters will not produce cracks, and its impact resistance at low temperatures is also very significant.

Insulation Performance:This product is an insulating product, and it will remain undamaged even in the event of accidental discharge. It is particularly safer to replace metal tiles in areas with frequent lightning and near high-voltage lines.

Application Scope

Factory buildings, steel structure plants, warehouses, farmers' markets, market passageways, carports, etc. It is particularly effective in corrosive factories such as ceramic factories, chemical plants, dyeing plants, smelting plants, and fertilizer plants.
