Learn how Galvalume alloy technology protects Siddhi Steel Doors against rust, termites, and harsh monsoon weather.
What is Galvalume (GL)?
Galvalume is a high-performance alloy coating containing 50% Zinc, 50% Aluminum & Silicon used to protect steel main entrance doors against oxidation and harsh weather.
What is the difference between GL and GI Steel?
Galvanized Iron (GI) uses a 100% zinc coating, whereas Galvalume (GL) incorporates 50% aluminum and silicon into zinc. This dual-action alloy delivers up to 4x higher rust immunity than ordinary GI steel.
What is Galvalume generally used for?
GL steel is specified for architectural products exposed to monsoon rain, extreme heat, and coastal humidity because of its superior anti-corrosion barrier.
What are the main advantages of Siddhi GL Doors?
Siddhi GL Steel Doors provide 100% termite immunity, zero rust degradation, high acoustic soundproofing (40dB), thermoset woodgrain finish, and heavy-duty multi-locking security.
