The material you choose for your curtain eyelets affects not just the appearance but the long-term durability, corrosion resistance, and suitability of the fitting for its environment. Brass, stainless steel, aluminium, and steel with decorative finishes all have distinct properties. This guide explains each material, its strengths and limitations, and the applications it is best suited to, so you can make the right specification every time.
Brass curtain eyelets
Brass is an alloy of copper and zinc, and it has been the benchmark material for curtain eyelets since the earliest days of metal haberdashery. Its enduring popularity is well deserved:
- Natural corrosion resistance: Brass does not rust. It develops a natural patina over time if left unfinished, but this does not affect structural integrity. In humid environments such as bathrooms, brass outperforms steel with surface finishes.
- Excellent malleability: Brass crimps cleanly and consistently, producing a tight, smooth flange without cracking. This is particularly important for large-diameter eyelets where the crimp must travel further.
- Aesthetic versatility: Brass accepts the widest range of decorative finishes of any eyelet material, including polished gold (natural brass), antique brass, satin nickel, chrome, gun-metal black, and brass-plated. This makes it the material of choice for premium interior projects where the eyelet finish must coordinate with other hardware.
Recommended for: Premium residential curtains, bathroom curtains, awnings and outdoor roller blinds, leather goods, nautical applications (with appropriate finish), commercial interiors.
Stainless steel curtain eyelets
Stainless steel (typically grade 304 or 316) is the hardest, strongest, and most corrosion-resistant metal used for curtain eyelets.
- Maximum corrosion resistance: Unlike surface-treated steel, stainless steel's corrosion resistance is inherent throughout the material. Grade 316 is specifically formulated to resist salt-water corrosion, making it the only correct specification for marine and coastal environments.
- Highest mechanical strength: Stainless steel eyelets withstand the greatest loads without distorting, making them the specification for industrial tarpaulins, heavy awnings, and refrigeration curtains.
- Hygienic and easy to clean: The smooth, non-porous surface of stainless steel does not harbour bacteria and tolerates strong cleaning chemicals. This makes it the preferred specification for food-industry environments.
- Self-finishing: Stainless steel has its own clean, bright appearance that requires no additional surface treatment, though it can be polished or brushed for decorative effect.
Recommended for: Marine environments, coastal installations, industrial tarpaulins and covers, refrigeration and cold-store curtains, food-industry environments, anywhere a long service life under extreme conditions is required.
Aluminium curtain eyelets
Aluminium offers a distinctive combination of properties that makes it the preferred material for specific applications:
- Exceptional lightness: Aluminium is approximately 65% lighter than brass of the same size. For lightweight voile or sheer curtains where every gram in the header affects the drape, aluminium eyelets are significantly preferable to heavier metals.
- Good corrosion resistance: Aluminium forms a natural protective oxide layer that resists corrosion well in most atmospheric conditions.
- Most economical metal eyelet: Aluminium is typically the lowest-cost metal eyelet option, which matters on large-volume projects.
- Anodising options: Aluminium can be anodised in a wide range of colours, which is useful for advertising banners and PVC tarpaulins where a coloured eyelet matching the banner design is required.
Recommended for: Lightweight and sheer curtains, net curtains, voiles, advertising banners and PVC mesh panels, applications where colour-matched eyelets are required.
Not recommended for: Heavy curtains, high-tension awnings or tarpaulins, marine environments (aluminium can react galvanically with stainless steel fittings).
Steel eyelets with decorative finishes
Steel eyelets are stamped from mild steel and then coated with a decorative finish. They offer a cost-effective middle ground between aluminium and solid brass:
- Good mechanical strength: Steel is stronger than aluminium and comparable to brass in tensile strength for eyelet applications.
- Medium price point: Steel eyelets are less expensive than brass or stainless steel, making them economical for volume projects where the environment is controlled.
- Wide range of finishes: Nickel (silver/satin, the most versatile), black/gun-metal (elegant, popular in fashion and contemporary interiors), brass-plated (gold look at lower cost than solid brass), chrome (bright mirror finish).
Recommended for: Indoor curtains in dry conditions, garment and footwear eyelets, temporary awnings, projects where the aesthetic of a metallic finish is needed at a competitive price.
Not recommended for: Humid rooms (bathroom), outdoor exposure, marine environments — the surface finish may be compromised over time and the underlying steel will then corrode.
