Galvanized Internal Corner – 100x75mm

The galvanized internal corner 100x75mm is a durable and precision-engineered component designed to strengthen and waterproof internal joints in gutter systems, downpipes, and other roofing edges. Crafted from high-quality galvanized steel, this internal corner ensures excellent corrosion resistance and long-term outdoor performance. Its asymmetrical L-shape (100mm × 75mm) provides a perfect fit for standard gutter dimensions while adding structural stability.

Superior Structural and Weatherproof Performance

Reinforced Corner Strength

• Impact Resistance: Protects vulnerable internal corners from mechanical stress and gutter sagging.

• Load Distribution: Supports water and debris weight evenly across the joint.

• Thermal Stability: Minimizes expansion and contraction under temperature changes.

Long-Lasting Weather Protection

• Corrosion-Resistant: Hot-dip galvanized coating withstands rust and environmental damage for decades.

• Water Diversion: 90° angle design ensures seamless water flow without leakage.

• UV Protection: Matte finish resists sun damage better than painted alternatives.

Easy Installation and Compatibility

• Pre-Drilled Holes: Optional perforations allow quick fixing with screws or rivets.

• Tool-Friendly: Can be cut with angle grinders, tin snips, or nibblers for custom fits.

• Sealant Ready: Flat surfaces accommodate silicone, butyl tape, or polyurethane sealants.

Installation Steps

1. Measure & Cut: Trim the galvanized internal corner to the desired length, deburring edges.

2. Dry Fit: Align in the gutter or joint and mark fixing positions.

3. Secure: Use stainless steel screws or pop rivets for a tight fit.

4. Seal: Apply gutter sealant along inner edges for water-tightness.

5. Test: Conduct a hose test to ensure no leakage.
