Eyelets used in awnings and tarpaulins operate in conditions that are fundamentally more demanding than those of curtain eyelets in an interior setting. They must resist high mechanical tension, prolonged outdoor exposure, UV radiation, wind buffeting, rain, and in many cases salt air. A poorly specified or incorrectly fitted eyelet in an awning or tarpaulin is not just an aesthetic failure — it is a safety risk. This guide covers everything you need to specify and install eyelets for awning and tarpaulin applications correctly.
Why awning and tarpaulin eyelets are different
When an awning or tarpaulin is under tension or exposed to wind, every eyelet along the edge becomes a load-bearing point. The forces involved are significantly greater than anything a curtain eyelet encounters. Consider:
- Wind load: A large awning or truck tarpaulin at motorway speeds can experience forces of several hundred newtons at each anchor point.
- Sustained outdoor exposure: Rain, UV radiation, temperature cycling, and salt air attack both the eyelet material and any surface coating.
- Vibration fatigue: Repeated wind-induced vibration gradually works the eyelet material, which is why the crimp must be perfectly executed and the eyelet material must be appropriate.
- Abrasion: Ropes, bungee cords, and hooks moving through eyelets under load cause progressive wear. Softer eyelet materials wear through more quickly.
Recommended eyelet types for awnings and tarpaulins
Brass eyelets
Brass is the most reliable general-purpose material for awning and tarpaulin eyelets. Its natural corrosion resistance means it does not depend on a surface coating that could be compromised by abrasion or weathering. Brass is sufficiently strong for the majority of residential and commercial awning applications, and its malleability ensures a reliable, crack-free crimp. It is the material used by professional awning and tarpaulin manufacturers across Europe.
Stainless steel eyelets
Stainless steel is the premium specification for coastal, marine, and industrial tarpaulin applications. Grade 316 stainless steel withstands salt-air corrosion that would eventually compromise even brass over many years. It also offers the highest mechanical strength of any standard eyelet material, making it the correct choice for heavy industrial covers, boat tarpaulins, and any application where maximum service life under extreme conditions is required.
DIN 7332 standard eyelets
In professional awning manufacture across Europe, the DIN 7332 standard specifies the dimensional tolerances and material grades for awning eyelets. Specifying DIN 7332-compliant eyelets ensures dimensional compatibility with professional press tools and consistent performance across production batches. When ordering eyelets for professional awning work, always request DIN 7332-compliant references.
Spacing and size recommendations
| Application type | Recommended spacing (centre to centre) | Recommended eyelet interior diameter |
|---|---|---|
| Residential light awning | 30–40 cm | 12–16 mm |
| Commercial awning | 25–35 cm | 16–20 mm |
| Advertising banner / PVC mesh | 40–50 cm | 12–14 mm |
| Industrial tent / large canopy | 20–30 cm | 20–40 mm |
| Truck / lorry tarpaulin | 15–25 cm | 16–20 mm |
As a general principle, the higher the load or wind exposure, the closer the spacing and the larger the eyelet interior diameter should be. Closer spacing distributes the load across more attachment points, reducing the force at each individual eyelet.
Fitting guide for awning and tarpaulin eyelets
- Reinforce the edges: Before fitting any eyelet, the tarpaulin or awning edge must be reinforced by folding over at least 3 cm of material and sewing or heat-welding it. This creates a double-thickness edge at every eyelet position, which is essential for withstanding the loads involved. Never fit eyelets through a single layer of awning fabric.
- Always use washers: Every awning or tarpaulin eyelet must be fitted with its matching washer. The washer distributes the load over a larger area of fabric and prevents the eyelet ring from pulling through under tension. Never omit the washer, even on temporary applications.
- Use a professional press for large eyelets: Eyelets above 14 mm interior diameter require a professional bench press or pneumatic press to produce a reliable crimp. Hand tools are inadequate for these sizes and will produce an inconsistent crimp that will fail prematurely under load.
- Check tension after fitting: Once all eyelets are fitted and the awning or tarpaulin is installed, check that the load is distributed evenly across all eyelets. If some eyelets are carrying significantly more load than others (visible as distortion of the fabric near those eyelets), the fixing rope or strap arrangement should be adjusted before the fitting is left in service.
Common mistakes to avoid
- Using aluminium eyelets outdoors: Aluminium is too soft for high-tension awning applications. Under sustained load, aluminium eyelets can deform, allowing the cord or hook to pull through. Reserve aluminium for light, low-tension applications such as advertising banners.
- Using eyelets that are too small: An eyelet whose interior diameter barely accommodates the rope or hook will concentrate wear at the top of the opening, rapidly enlarging the hole and weakening the fitting. Always allow adequate clearance.
- Fitting without a washer: This is the single most common cause of eyelet pull-through failure in tarpaulin applications. The washer is not optional.
- Spacing too wide: Excessively wide spacing concentrates too much load at each eyelet. In high-wind conditions, individual eyelets will be overloaded and may tear through the tarpaulin edge.
- Using steel eyelets with surface finishes outdoors: The surface finish on plated steel eyelets will be compromised by outdoor weathering, leaving the underlying steel exposed to corrosion. Use solid brass or stainless steel for any outdoor awning or tarpaulin application.
