1. Aluminum Alloy Slats

Aluminum alloy slats are one of the most common types of roller shutter slats, favored for their lightweight, corrosion resistance, and aesthetic appeal.

Key Parameters

• Thickness: Typically 0.8mm–1.2mm, with high-end commercial doors reaching 1.5mm.

• Surface Treatment: Anodized, powder-coated, or fluorocarbon-coated to enhance weather resistance and UV protection.

• Color Options: Customizable colors to match various architectural styles.

Advantages

• Lightweight: Easier to roll compared to steel slats, reducing motor load and extending lifespan.

• Corrosion Resistance: Suitable for coastal or high-humidity areas, resistant to rust.

• Aesthetic Appeal: Smooth surface complements modern architectural designs.

Applications

• Shopfronts

• Residential garages

• Office building exteriors

  
  

2. Stainless Steel Slats

Stainless steel slats are known for their high strength and corrosion resistance, available in 201, 304, and 316 stainless steel to suit different environmental needs.

Key Parameters

• Material:

• 201 Stainless Steel: Higher manganese content, moderate corrosion resistance, suitable for dry inland areas.

• 304 Stainless Steel: Contains 18% chromium and 8% nickel, offering good corrosion resistance for general use.

• 316 Stainless Steel: Includes molybdenum, providing excellent corrosion resistance, especially for high-salinity environments.

• Thickness: 0.6mm–1.5mm, with industrial-grade slats up to 2.0mm.

• Surface Treatment: Brushed, mirror, or sandblasted finishes for enhanced aesthetics.

Advantages Comparison

Applications

• 201 Stainless Steel: Standard shops, temporary structures

• 304 Stainless Steel: Banks, shopping malls, commercial spaces

• 316 Stainless Steel: Chemical plants, coastal buildings

3. Color Steel Slats (Galvanized Steel Slats)

Color steel slats are made from galvanized steel with a colored coating, offering a balance of affordability and durability.

Key Parameters

• Base Material: Galvanized steel (zinc layer ≥20μm).

• Coating: Polyester (PE), fluorocarbon (PVDF), etc., affecting weather resistance.

• Thickness: 0.3mm–0.8mm, with industrial doors up to 1.0mm.

Advantages

• Cost-Effective: More economical than aluminum or stainless steel.

• Moderate Strength: Suitable for basic security needs.

• Color Variety: Customizable colors through coating.

Applications

• Warehouses, logistics centers

• Small shops

• Temporary construction barriers

4. Transparent/Semi-Transparent Slats (Polycarbonate or PVC)

These slats use light-transmitting materials, ideal for spaces requiring natural light or display purposes.

Key Parameters

• Material: Polycarbonate (PC) or PVC; PC offers better impact resistance.

• Light Transmission: 70%–90%, with frosted options for privacy.

• Thickness: 1.5mm–3.0mm; PC slats are more impact-resistant.

Advantages

• Natural Lighting: Reduces indoor lighting needs, saving energy.

• Lightweight: Suitable for manual roller shutters.

• UV Resistance: PC material prevents UV degradation.

Applications

• Storefront displays

• Sunrooms

• Parking lot entrances

5. Fireproof Slats (Composite Metal + Fireproof Core)

Fireproof slats feature a multi-layer structure with fire-resistant fillers to achieve flame retardancy.

Key Parameters

• Fire Rating: Class A (non-combustible), Class B (flame-retardant), with 30–120 minutes of fire resistance.

• Structure: Double-layer steel with rock wool or aluminum silicate fiber filling.

• Thickness: 40mm–80mm; thicker slats offer better fire resistance.

Advantages

• Fire Resistance: Slows fire spread, enhancing safety.

• Sound and Heat Insulation: Filler layers reduce noise and heat transfer.

Applications

• Chemical plants, gas stations

• High-rise building fire compartments

• Data centers

6. Silent Slats (Noise-Reducing Structure)

Silent slats incorporate special designs (e.g., rubber seals, multi-layer composites) to minimize operational noise.

Key Parameters

• Noise Level: ≤50 dB (standard slats: 60–70 dB).

• Structure: Nylon guide rollers and noise-absorbing strips between slats.

Advantages

• Quiet Operation: Ideal for residential areas or nighttime use.

• Reduced Wear: Noise-reducing design decreases rail friction, extending lifespan.

Applications

• Residential garages

• Hospitals, schools

• High-end homes

FAQ (Frequently Asked Questions)

Q1: How to choose between 201, 304, and 316 stainless steel slats?

A: 201 is budget-friendly for dry inland areas; 304 suits most general environments; 316 is designed for high-corrosion areas like coastal or industrial zones.

Q2: How to select the right thickness for roller shutter slats?

A: Residential: 0.8mm–1.2mm; commercial: ≥1.2mm; industrial: ≥1.5mm.

Q3: Are transparent slats secure?

A: Polycarbonate (PC) is impact-resistant but less secure than metal slats; suitable for low-risk areas.

Q4: Do fireproof slats really work?

A: Yes, certified fireproof slats can resist flames for 30–120 minutes, depending on the fire rating.

Q5: How to reduce roller shutter noise?

A: Opt for silent slats or install nylon guide rollers and lubricate the chain regularly.
