Product characteristics

 
features-image
The plugs are made of polyethylene
– plastic with versatile applications. Polyethylene
is characterised by high abrasion resistance,
resistance to environmental stress corrosion, high
dimensional stability (even at low temperatures),
very good chemical resistance and low water absorption.
It is resistant to changing weather conditions and UV radiation.
The rough surface prevents
scratches in bulk packaging.
The matte texture of the top
part of the plug contributes to its neat appearance.
The bottom part of the plug
consists of the core and projecting “slats”.
When the plug is being driven into the profile,
the slats adjust to profile wall thickness.

Rectangular end caps made of plastic using the injection-moulding process, designed for sealing profile ends. The end cap consists of an outer part that extends beyond the profile and an inner part, the so-called core, which is inserted into the profile. The matte texture of the top surface gives the cap an aesthetic appearance. The rough finish prevents scratches in bulk packaging. The lower part of the end cap is composed of the core and protruding “lamellas”. During installation, the lamellas adjust to the wall thickness of the profile.

End caps are widely used in constructions made of steel profiles, fencing systems, various machines and devices, workshop furniture, playground equipment, as well as other garden architecture elements. They are used in the furniture, machinery, electrotechnical and construction industries.

Standard colours: black, grey, white. Other colours available on request.

Rectangular Profile End Caps

Constructions made from rectangular profiles require proper finishing that ensures both protection and an aesthetic appearance. End caps for rectangular profiles are essential components that protect open profile ends from moisture, dust, and other contaminants. Made from high-quality polyethylene, they offer durability and weather resistance while giving any installation a professional look.

Applications and Benefits of Rectangular Profile End Caps

End caps for rectangular profiles are not only aesthetic elements but, above all, practical protective solutions. Their main function is to protect the interior of the profiles from harmful external factors such as water, dust, or other contaminants. Thanks to their tight fit, the caps effectively protect steel, aluminium, and plastic profiles from corrosion and degradation, significantly extending their lifespan.

In addition to their protective function, the caps give constructions a professional, finished appearance, enhancing the aesthetic value of the entire installation. When colour-matched properly, the caps blend harmoniously with the profile, creating a cohesive look. This is especially important for visible structures such as furniture, fences, or interior elements, where every detail matters.

The caps are made from high-quality polyethylene, a material distinguished by exceptional resistance to UV radiation, frost, and changing weather conditions. As a result, they maintain their properties over long periods without losing colour or elasticity. This durability makes rectangular profile end caps an ideal solution for both indoor and outdoor applications.

Dimensions and Fitting of Rectangular Profile End Caps

The range of rectangular profile end caps includes a wide selection of sizes tailored to the most commonly used profile dimensions on the market. Available are models for small profiles used in furniture and lightweight constructions, as well as large profiles for construction and industrial applications. This ensures that every customer can find a product ideally suited to their needs without modifications.

Mounting the end caps is extremely simple and quick, providing time savings during installation work. The caps can be manually pressed into the profile opening without the need for special tools or adhesives. Thanks to their well-designed gripping elements, they sit securely in the profile, minimizing the risk of accidental removal. This ease of installation is particularly appreciated by professionals working on large projects.

Summary

Rectangular profile end caps are essential components for any construction that uses metal or plastic profiles. Thanks to high-quality materials and precise manufacturing, they provide effective protection against moisture, dust, and contaminants, while giving the entire construction an aesthetic and professional look.

The flexibility of fit, achieved through the lamella system, allows the caps to accommodate profiles with varying wall thicknesses, greatly simplifying selection and installation. The ability to install them without tools further enhances their convenience.

A wide selection of sizes and colours, along with the option for custom orders, allows for perfect adaptation to specific functional and aesthetic requirements. Whether your project involves industry, construction, or furniture manufacturing, Tulplast offers rectangular profile end caps that meet the highest standards of durability, functionality, and appearance.
