Screw Length: 75mm, 90mm, 100mm (selected based on purlin thickness)
Waterproof Cap Diameter: Typically 25mm-30mm
Screw Specification: #75 (Diameter: 4.2mm-4.8mm)
Screw Length: 75mm, 90mm, 100mm (selected based on purlin thickness)
Waterproof Cap Diameter: Typically 25mm-30mm
Screw Waterproofing and Drip Protection: Used at the eaves of villas, residential buildings, and commercial structures to prevent water infiltration through screw holes and provide drip edge protection.
Sealing and Leak Prevention: Applied to windowsills, lintels, and awnings to seal screw holes and prevent leakage.
System Integration: Compatible with roofing tiles, gutters, and eave plates to enhance the building’s drainage and moisture-proofing system.
Superior Waterproof Sealing
The ASA waterproof cap and screw form a precision dual-sealing structure that effectively prevents rainwater penetration through screw holes. Passes IPX5 waterproof rating tests.
Exceptional Weather Resistance
ASA material resists UV radiation and extreme temperatures (-40°C to 120°C). Matches the service life of resin tiles with no brittleness or color fading for 20 years.
Anti-Corrosion Protection
The #75 galvanized screw withstands 500-hour salt spray tests without rusting. Ideal for coastal and industrial corrosive environments.
Easy and Efficient Installation
Snap-on design allows tool-free installation, increasing施工 efficiency by 50% and reducing labor costs.
Wide Compatibility
Compatible with various roofing materials (resin tiles, daylighting panels, metal tiles) of 2.0-3.0mm thickness. Fits screw holes of 4-5mm diameter.
Scientific Material Selection: ASA engineering resin + galvanized steel screw for synergistic weather resistance.
Precision Structure: Built-in sealing ring automatically compresses during screw tightening to form a secure seal.
Pressure Dispersion: The cap base distributes screw pressure to prevent tile cracking or deformation.
Color Customization: 10+ standard colors (e.g., brick red, slate gray, snow white) with custom color matching support.
Eco-Certifications: Complies with ROHS and REACH environmental standards, free of heavy metal pollution.
Pre-drilling Preparation: Pre-drill holes at the tile wave peaks. The hole diameter should be 2-3mm larger than the screw diameter.
Installation Sequence: First sleeve the waterproof cap onto the screw, then insert it through the tile hole and tighten into the purlin.
Tightening Force: Tighten until the waterproof cap fully contacts the tile surface, but avoid over-tightening.
Installation Position: Fix at the tile wave peaks; avoid installation at wave valleys.
Spacing Requirement: Maintain appropriate fixing spacing according to design requirements.
Execution Standard：
GB/T 15856.1-2002 Self-tapping Screw Standard
JC/T 2054-2011 Synthetic Resin Tiles
T/CBMCA 018-2021 Reinforced Synthetic Resin Tiles
Transportation：
Sealed Packaging: Packed in sealed plastic bags to prevent moisture ingress.
Anti-Rust Treatment: Implement moisture and rust prevention measures during transportation.
Avoid Mixed Packaging: Separate packaging for different specifications and sizes.
Handle with Care: Avoid packaging damage to prevent part loss.
It can be transported by sea, land, and air, usually through container transportation
Storage Conditions：
Ndoor Storage: Store in a cool, dry, and well-ventilated indoor area, avoiding direct sunlight and rain.
Proper Stacking: Stack flat with a height not exceeding 1 meter.
No Heavy Loads: Do not place any heavy objects on top to prevent deformation.
