Consmos Metal, a leading provider of advanced building materials, is proud to offer a comprehensive range of high-performance Color Steel Tiles, officially known as Color Profiled Steel Sheets. Engineered for durability, efficiency, and aesthetic flexibility, this product is a cornerstone for modern industrial, commercial, and civil construction.

What are Color Steel Tiles?
Color steel tiles are manufactured by coating cold-rolled or hot-dip galvanized/galvalume steel substrates with primer and colored organic coatings, followed by baking and curing. These sheets are then roll-formed into various profiled shapes. Renowned for their strength and versatility, they are extensively used in industrial workshops, warehouses, agricultural markets, prefabricated houses, and complete steel structure enclosure systems for roofs and walls.

I. Core Product Classifications

1. By Substrate Material:

Hot-dip Galvanized (GI): Features a tightly bonded zinc layer for strong rust resistance and excellent cost-performance. Ideal for most industrial and civil buildings, especially in humid environments.

Hot-dip Aluminized Zinc (AZ): Offers superior corrosion and oxidation resistance compared to GI, ensuring a longer service life. The recommended choice for coastal areas with high salt fog or high-humidity workshops.

Cold-Rolled Substrate (CR): A cost-effective option protected primarily by the surface coating. Best suited for dry indoor environments or temporary structures, not recommended for long-term outdoor exposure.

2. By Wave Shape (Profile):

Standing Seam (e.g., Angle Lock): High-profile panels installed with interlocking seams. Offers exceptional sealing, and superior wind and snow load resistance, perfect for large-span factory roofs.

Roof Sheeting (e.g., Type 840/900): Balanced profile height for easy installation and cost-effectiveness. Versatile for both roofing and wall applications.

Wall Sheeting (e.g., Type 950/980): Low-profile, flatter surface designed primarily for aesthetic and protective wall cladding.

Tile-Imitation Profile: Mimics traditional clay or slate tiles. Combines durability with decorative appeal, perfect for scenic spots and residential projects.

3. By Coating Type:

Polyester (PE): Provides bright colors, good adhesion, and general weather resistance. A cost-effective solution for inland areas with a typical service life of 5-8 years.

Silicone Modified Polyester (SMP): Delivers better UV resistance and flexibility than PE. Suitable for moderate corrosion environments, lasting 8-12 years.

High-Durability Polyester (HDP): Contains advanced resins for enhanced chalk and fade resistance. Ideal for harsh outdoor conditions, with a lifespan of 10-15 years.

Polyvinylidene Fluoride (PVDF/Fluorocarbon): Offers premier corrosion, UV, and chemical resistance with exceptional color retention. Designed for coastal and industrial zones, with a service life exceeding 15-20 years.

II. Key Performance & Selection Parameters
Critical specifications for informed procurement include:

Substrate Thickness (0.3mm-0.8mm): Determines strength and load capacity.

Coating Thickness: Front (20-30μm) and back (10-15μm) coating levels impact longevity.

Zinc Coating Mass (e.g., Z100, Z275): Higher grams per square meter (g/㎡) indicate stronger rust protection.

Effective Cover Width: The actual width a sheet covers after installation, crucial for quantity calculation.

Weather Resistance: Ranks as PVDF > HDP > SMP > PE based on UV and fade resistance.

Fire Rating: The steel sheet is non-combustible (Class A), though composite panels require core material evaluation.

III. Advantages and Considerations

Advantages:

High Cost-Performance: Lightweight (10-14kg/㎡) reduces structural load, enables fast installation, and shortens project timelines.

Aesthetic Flexibility: Available in a wide spectrum of colors to match any architectural design.

Superior Protection: Excellent waterproofing, rust, and corrosion resistance for diverse climates.

Sustainable: Fully recyclable at end-of-life, supporting green building initiatives.

Practical Considerations:

Insulation requires composite panels with core materials like rock wool.

The coating must be maintained; scratches should be repaired promptly to prevent substrate corrosion.

Wind uplift resistance depends heavily on professional installation and correct fastener protocols.

IV. Common Application Scenarios

Industrial Buildings: Factories, warehouses, logistics centers.

Civil & Commercial Structures: Agricultural markets, parking canopies, prefab houses, and rural residential roofs.

Temporary Facilities: Site offices, exhibition booths, and disaster-relief housing.

Architectural Features: Decorative facades, partitions, and signage enclosures.

V. Procurement and Usage Guidance

1. Select for Environment: Choose AZ substrate with PVDF coating for coastal regions; GI with PE/SMP may suffice for dry inland areas.

2. Inspect Upon Delivery: Verify substrate thickness, zinc layer mass, and coating quality for scratches or color variance.

3. Ensure Professional Installation: Maintain minimum roof slope, use recommended fasteners at crests, and apply sealant on overlaps.

4. Plan Simple Maintenance: Conduct periodic inspections and repair any coating damage with specialized touch-up paint.
