Top-Quality Square Fitting Solutions for Innovative and Sturdy Structures

Fisher Alvin’s square fittings are designed for constructing robust frameworks using Square Hollow Section (SHS) or box section steel. These fittings are ideal for applications like signage frames, industrial-style furniture, storage racks, and shop display frames, offering a strong, weld-free solution that doesn’t require specialised skills or tools.
While these fittings are suitable for many structural projects, they are not recommended for safety applications such as handrails or guardrails. For these purposes, our Key Clamp systems are specifically designed to meet safety requirements.

The Benefits of Using Square Tube Connectors

Fisher Alvin’s square tube connectors provide a versatile and long-lasting solution for a variety of projects. Whether you’re building shelves, tables, or signage frames, these connectors offer a reliable and easy-to-assemble alternative to traditional methods like welding or drilling. By using bolts and nuts, you can create strong and secure connections without the need for special equipment. This also allows for quick modifications to your designs, making it easy to expand or adjust structures as needed.
Our square fittings are made from high-quality materials, including galvanised steel and malleable cast iron, ensuring maximum durability. The galvanised finish offers protection against temperature fluctuations and corrosion, making the fittings suitable for both indoor and outdoor use. For projects that require a more aesthetic finish, we also offer matt black e-coated options, which are ideal for indoor applications only.

Key Components and Sizes of Fisher Alvin’s Square Fittings Range

Our square fittings come in two standard sizes: 40×40 mm and 25×25 mm, making them suitable for a wide variety of projects. Both sizes are available in galvanised steel and matt black e-coating, ensuring they are supplied in the finish that best suits your needs. Each fitting is manufactured to BS EN ISO 1461 standards, providing long-lasting performance.

Key components in our range include:

  • T-Pieces and Elbows for 90° connections, allowing you to easily fix tubing at different angles.
  • Footplates for securely anchoring structures to floors or walls, ensuring a stable support system.
  • Cross Joints for joining multiple tubes at right angles, providing maximum stability.
  • Straight Couplings for joining sections of square tubing in-line, enabling seamless connections.

These components are designed for easy assembly using just an Allen key, ensuring quick installation. You can easily tighten the bolts to lock the fittings in place, creating a sturdy structure that’s built to last.

Square Fittings vs Traditional Joining Methods

Traditional joining methods, such as welding or using threaded connections, can be difficult and time-consuming. With Fisher Alvin’s square fittings, you can build strong frameworks more efficiently. These fittings provide a cost-effective solution, saving you time and money. You can easily cut and join tubes using basic tools, without the need for a professional welder.

Our modular design allows you to maintain and adjust your structures, offering flexibility for future changes. If you need to expand or alter your design, square fittings are easily disassembled and reused, making them an excellent choice for projects that require frequent updates.

Accessibility and Compliance

Although our square fittings are not designed for safety applications, they are perfect for creating accessible furniture like tables and shelves. For safety-specific projects, we recommend looking at our Key Clamp systems, which are fully compliant with safety regulations and accessibility standards such as DDA (Disability Discrimination Act).

Quality, Durability, and Aesthetic Appeal

Our square fittings are manufactured from high-quality materials, ensuring they meet the principle of longevity and reliability. The square shape is particularly effective for constructing flat-topped surfaces like desks, tables or workbenches, offering a sleek, professional look for modern environments.
Fisher Alvin strives to provide a complete range of fittings that cater to both functional and aesthetic needs. Whether you’re building signage for a store or designing a custom piece of furniture, our selection of square fittings will help you achieve the look and durability you need. Each fitting is designed to support the structure and offer flexibility, ensuring that your project is completed to the highest standard.
