Aluzinc Eave Trim (Drip Edge)
Precision Edge Protection for Long-Lasting Roof Performance.
The Aluzinc Eave Trim, also known as the Drip Edge, is a critical roofing accessory installed along the lower edge of the roof where sheets meet the fascia board and gutter system. Though often overlooked, it plays a vital structural and protective role in ensuring proper water runoff, preventing timber decay, and enhancing the aesthetic finish of the roofline.
Manufactured from premium Aluzinc-coated steel (AZ150 grade), our eave trims are engineered for superior corrosion resistance, structural integrity, and long-term performance in demanding environments.
Why Aluzinc is Superior for Eave Trim
Compared to plain galvanized steel, Aluzinc offers:
Up to 2–4x longer corrosion resistance
Better heat reflectivity
Reduced red rust formation
Longer structural lifespan
This makes it ideal for:
Coastal regions
Industrial zones
High rainfall environments
Long-term construction projects
Primary Functions of an Eave Trim
1. Directs Water into the Gutter
The eave trim channels rainwater from the roofing sheets directly into the gutter system, preventing water from:
Flowing behind gutters
Seeping into fascia boards
Damaging timber rafters or wall tops
This is especially important in heavy rainfall regions and coastal environments.
2. Protects Fascia and Structural Members
Without an eave trim, water can:
Rot wooden fascia boards
Cause paint blistering
Encourage mold growth
Weaken wall plates and trusses
The Aluzinc eave trim acts as a protective shield between roofing sheets and structural timber.
3. Prevents Wind-Driven Rain Intrusion
In areas with strong winds, rain can be blown upward under the roofing sheet. The eave trim seals this vulnerable edge and reduces:
Water backflow
Capillary action
Internal ceiling damage
4. Enhances Roofline Aesthetics
A properly installed eave trim creates:
A straight, clean roof edge
A professional architectural finish
Improved visual alignment between roof and gutter
For premium projects, this detail elevates the entire structure.
Material Composition – AZ150 Aluzinc Coating
Our eave trims are produced from high-quality steel coated with an Aluminium-Zinc alloy for enhanced durability.
Aluzinc Coating Composition:
55% Aluminium (Al)
43.4% Zinc (Zn)
1.6% Silicon (Si)
Coating Grade:
AZ150 (150g/m² coating mass total, both sides)
Base Steel Thickness:
Typically matches roofing sheets (0.40mm – 0.50mm or as specified)
This alloy combination provides:
Aluminium → Superior corrosion resistance
Zinc → Active sacrificial protection (self-healing at scratches)
Silicon → Enhanced coating adhesion and stability
