Steel Tubes, Box Sections and End Caps for Fencing and Metal Structures

Steel tubes, box sections and end caps are the structural and finishing components used to build or complete virtually any steel structure.

In this Fenceshop.eu category, you will find raw steel and galvanized steel profiles, including round tubes, square and rectangular box sections, solid round bars, flat bars, L profiles (angle irons) and protective end caps for closing open tube and box section ends.

These products are designed for anyone building, repairing or extending fences, pergolas, gates and metal structures, with the convenience of receiving steel components directly at home, cut to size and ready for assembly.

More specifically, this category includes a wide range of components such as fence tubes, galvanized tubes, raw steel tubes, steel box sections, square box sections, rectangular box sections, solid round bars, flat bars, angle irons, post caps, square caps, round caps, rectangular caps, steel for pergolas, steel for gates, and cut-to-size steel sections.

The common goal? Finding the correct dimensions and compatibility for the structure you intend to build.

Square and Rectangular Steel Box Sections for Every Structure

Steel box sections are hollow structural profiles with square or rectangular sections, widely used for frames, uprights and load-bearing structures.

Fenceshop.eu offers a broad range of sizes, from the lightweight 20x20 Square Box Section through to the 60x60 Square Box Section and 100x100 Square Box Section for more demanding structural applications.

For specific requirements, Rectangular Box Sections are also available, including the 40x15 Rectangular Box Section and 80x60 Rectangular Box Section, ideal where an elongated profile is required for rails, frames or gate structures.

Choosing the correct section size is essential to ensure structural rigidity. An undersized box section may flex under load, while an oversized profile unnecessarily increases weight and costs.

Raw and Galvanized Round Steel Tubes

Round steel tubes are among the most popular profiles for fence posts, uprights and tubular structures.

The range clearly distinguishes between raw steel and galvanized steel. The Raw Steel Tube Ø 48 and Raw Steel Tube Ø 60 are ideal for users who intend to paint or treat the steel themselves, while the Galvanized Tube Ø 48 and Galvanized Tube Ø 60 already provide corrosion protection, making them ideal for outdoor use without additional treatment.

A galvanized tube is often the most practical choice for fencing and outdoor structures because it offers long-term resistance against rust and weathering.

Before placing an order, it is essential to verify the diameter listed in the product specifications to ensure compatibility with existing posts, fittings and connectors. A tube with the wrong dimensions simply will not fit.

For lighter or decorative structures, smaller diameters are also available, including the Raw Steel Tube Ø 25.

Solid Round Bars, Flat Bars and Angle Irons

This category also includes solid steel profiles and angular sections used for reinforcement, cross members and fabrication work.

Solid Round Bars such as the Ø 12 Round Bar and Ø 16 Round Bar are commonly used for railings, stakes and structural details, while Solid Square Bars such as the 14x14 Square Bar are particularly suitable for security grilles and decorative metalwork.

Flat Bars including the 40x8 Flat Bar and 60x8 Flat Bar are widely used for base plates, brackets and structural connections, while Angle Irons such as the 40x40 Angle Iron and 60x40 Angle Iron are ideal for frames, supports and structural assemblies.

The variety of available profiles makes this category a valuable resource for both professional metal fabricators and DIY enthusiasts.

End Caps: Finishing and Protection

End Caps are designed to close the ends of steel tubes and box sections, preventing water ingress while giving the structure a professional finished appearance.

For example, the Black PVC Square End Cap is ideal for closing and protecting square steel box sections in either raw or galvanized steel. Rectangular End Caps and Round End Caps are also available for other profile types.

Closing fence posts with end caps is not only an aesthetic improvement. End caps protect the inside of the profile from rainwater, reducing the risk of internal corrosion and significantly extending the service life of the structure.

This small accessory can make a substantial difference to the durability of a fence, especially in the case of exposed tubular fence posts.

Compatibility, Matching Components and Installation

For a strong and durable result, tubes and box sections should always be selected together with compatible structural components.

They can be combined with Posts, Brace Bars and Post supports, choosing diameters and lengths according to the selected post type. To create secure structural connections, suitable Structural pipes and Support plates should be used.

To complete a fencing system, these steel profiles can also be integrated with products from the Mesh for Fencing, Modular Panel Fencing and Gates categories.

Before purchasing, it is always advisable to verify internal and external dimensions, section sizes and lengths to avoid compatibility issues.

In conclusion, the Steel Tubes, Box Sections and End Caps category is the ideal reference point for anyone seeking high-quality steel components for fencing and metal structures: square and rectangular box sections, raw and galvanized tubes, round bars, flat bars, angle irons and protective end caps.

Whether you are building a fence, pergola, gate or a small steel structure, you will find profiles fully compatible with the entire Fenceshop range.

Check the sections you require, choose raw or galvanized steel according to the intended application, and order your tubes, box sections and end caps online to create a strong, long-lasting structure.
