Product Introduction

A product is a type of metal roofing system that provides enhanced weather resistance and durability. It highlights two interlocking creases (consequently "twofold lok") that make a secure, watertight association between adjoining metal boards. Commercial, mechanical, and high-end private stuff uses this plan all the time.

Common Materials:

• Galvanized Steel ：G-90
• Galvalume：Aluminum-Zinc Coated Steel
• Aluminum：Lightweight & corrosion-resistant
• Copper or Zinc ：Premium, decorative options

Key Features of Double Lok Standing Seam

• Interlocking Seams：The panels have a double-folded seam that locks together mechanically (often with a seaming tool), providing superior strength and weather resistance.
• Concealed Fasteners：The panels are attached with hidden clips, reducing the risk of leaks and improving aesthetics.
• Thermal Expansion Accommodation： The floating clip system allows for natural metal expansion and contraction.
• High Wind & Uplift Resistance：The double-lock seam provides excellent resistance to strong winds and negative pressure (common in hurricanes or storms).
• Low Maintenance：The durable metal (usually steel or aluminum) resists corrosion, fading, and extreme weather.

Advantages

• Superior Weatherproofing：Better than single-lock systems due to the extra seam fold.  
• Long Lifespan： Can last 30-50+ years with proper installation.  
• Sleek, Modern Look：Clean lines with no exposed screws.  
• Energy Efficiency： Can be paired with insulation for better thermal performance.
