The Union of the Comoros, comprising the beautiful islands of Grande Comore, Anjouan, and Mohéli, presents a unique challenge for construction materials. Being a volcanic archipelago in the Indian Ocean, the local environment is characterized by high humidity, intense UV radiation, and severe salt spray from the ocean. Traditional galvanized steel often falls short in these conditions, leading to premature red rust and structural failure.
As a leading Galvalume Steel Sheet Factory and Supplier for Comoros, Handan BLS Structural Steel provides a technical paradigm shift. Our Galvalume products (55% Aluminum, 43.4% Zinc, and 1.6% Silicon) offer 3 to 6 times the corrosion resistance of standard galvanized sheets. This "Information Gain" is critical for Comorian developers: by choosing our Al-Zinc alloy, you are effectively doubling the service life of industrial warehouses, fishery cold storage, and residential roofing across the islands.
Supporting the modernization of the capital, our lightweight Galvalume sheets reduce structural load-bearing requirements, making them ideal for rapid urban expansion and commercial complexes.
The Comorian economy relies heavily on the blue economy. Our AZ150+ coated sheets are engineered to withstand the corrosive atmosphere of seaside fish processing plants and port warehouses.
With Comoros moving toward solar energy, our Galvalume sheets provide the high thermal reflectivity necessary to keep substations cool and the structural integrity to support PV mounting systems.

Navigating the import requirements in Comoros requires a partner who understands both international quality standards and local logistical nuances. Our products are fully compliant with ASTM, JIS, and EN standards, which are highly regarded by Comorian engineers. Furthermore, we provide detailed "Certificate of Analysis" (COA) for every batch, detailing the precise Al-Zn coating weight and mechanical properties.
They are essentially the same. "Galvalume" is a trademarked name often used in the Americas, while "Aluzinc" or "Zincalume" is common in Europe and Asia. Both refer to the 55% Al, 43.4% Zn, and 1.6% Si coating that offers superior corrosion resistance.
Due to the high salinity, we strongly recommend an AZ150 (150g/m²) coating. For mild inland areas, AZ100 may suffice, but AZ150 provides the necessary protection against the Comorian maritime climate.
Typically, the sea freight from Tianjin or Qingdao port to Moroni takes between 35 to 45 days, depending on transshipment schedules at major hubs like Jebel Ali or Port Louis.
Yes, we can match any RAL color code. For Comoros, we recommend lighter colors (like RAL 9002 or RAL 9003) to maximize solar reflectance and reduce indoor temperatures.
Yes, the coating is stable and non-toxic, making it safe for rainwater harvesting systems, which are vital for freshwater supply in many parts of the Comoros islands.
With proper installation and an AZ150 coating, our Galvalume sheets can last 20-30 years in Comoros without significant corrosion, compared to 5-10 years for standard galvanization.
