Cap for square fencing posts NSK 16

Available Sizes of External Caps for Square Fence Posts

Fence structures come in various dimensions, which is why selecting the correct cap size is of key importance. In our range, you will find external caps for square fence posts in a wide variety of sizes – from the smallest 15x15 mm, through popular 40x40 mm and 60x60 mm, up to solid 120x120 mm. Such a wide selection guarantees a perfect fit for any type of fence, regardless of its purpose or dimensions.

When choosing the correct cap size, the external dimensions of the fence post should be measured. The cap should fit tightly to the profile to ensure effective protection against water and dirt penetration. A cap that is too loose may lead to moisture accumulation, while one that is too tight can cause installation difficulties or even cracking.

Smaller cap sizes (20x20 mm, 30x30 mm) are ideal for lightweight structures such as decorative fences or small gates. Medium-sized caps (40x40 mm, 50x50 mm) are the most popular choice for standard residential fencing, offering an optimal balance between strength and aesthetics. The largest caps (80x80 mm, 100x100 mm, 120x120 mm) are designed for heavy-duty industrial fences.

Materials and Durability of External Caps for Square Posts

External caps for square fence posts manufactured by Tulplast are made from high-quality LDPE polyethylene, a material with outstanding performance characteristics. This advanced polymer offers excellent resistance to UV radiation, ensuring that the caps do not fade or become brittle even after many years of exposure to intense sunlight.

The material is also highly resistant to extreme temperatures – from severe frost to hot summer days – maintaining its mechanical properties within a temperature range of -40°C to +80°C.

The caps effectively protect metal profiles against corrosion, which is the primary threat to the durability of fence structures. Lack of proper protection of the upper edges of posts leads to water accumulation inside the profiles, resulting in accelerated internal corrosion and a significant reduction in the fence’s lifespan.

Thanks to the use of high-quality plastic, Tulplast external caps retain their parameters for many years of use – they do not discolor, crack, or crumble under changing weather conditions. Investing in proper fence post protection is a cost that pays off many times over by extending the service life of the entire structure.

Types and Applications of External Caps for Square Posts

External caps for square fence posts are available in several basic color variants, allowing for perfect matching with different types of fencing. Our offer includes caps in the following colors: black (RAL9005), graphite, anthracite (RAL7016), grey (RAL7040), and green (RAL6005).

The correct color selection plays a key role in the overall fence aesthetics – black and anthracite caps perfectly complement modern residential fences, graphite and grey are universal solutions for most structures, while green caps blend seamlessly with park and forest fencing.

It is worth emphasizing that external caps for square posts are not limited to fencing applications only. Their universal shape and high durability make them suitable for many other industries. In furniture manufacturing, they serve as an elegant finish for steel frames, while in electrical engineering they protect profile ends against moisture and contaminants.

The caps are also widely used in machinery and industrial equipment construction, as well as in garden architecture – for pergolas, gazebos, and other outdoor structures. Thanks to easy installation and high durability, Tulplast external caps are a practical solution wherever square profiles require protection and an aesthetic finish.
