Embracing Excellence: Why Sign Trade Supplies Loves Aluminium


In the dynamic world of sign manufacturing, the choice of materials plays a pivotal role in ensuring durability, versatility, and aesthetic appeal. Sign Trade Supplies, a prominent supplier of aluminium sign posts, standard profiles, bespoke extrusions, and fixings, has a particular affection for aluminium. In this blog post, we delve into the reasons behind this love affair and explore why aluminium stands out as the material of choice for the sign industry.

1. Customisation and Versatility:

The sign industry thrives on creativity and customisation. Aluminium's malleability allows Sign Trade Supplies to offer an extensive range of standard extrusions and bespoke profiles. Whether it's a unique shape or a specific size requirement, aluminium can be manufactured to meet diverse design needs.


Finishing options for aluminium compliment the flexibility of the design. From simple anodising, durable powder coats, all the way to special wood grain effect. There aren’t many barriers to what you can achieve with a humble aluminium extrusion matched with the perfect finish.

2. Sustainability and the Environment:

Aluminium stands as a shining example of sustainability in material choices due to its exceptional recyclability. Unlike many other materials, aluminium can be recycled repeatedly without losing its intrinsic properties. The recycling process requires significantly less energy compared to primary production, making it an environmentally responsible option. This inherent recyclability contributes to a circular economy, reducing the environmental footprint associated with aluminium production and aligning with the global push towards more sustainable practices.

3.Exceptional Durability:

Durability is non-negotiable in the world of signage, where products are exposed to various weather conditions and external elements. Aluminium boasts impressive corrosion resistance improved more so when finished with protective coatings. 

These properties ensure sign blanks, sign posts and extrusions systems remain intact even in harsh environments. Sign Trade Supplies takes pride in providing products that stand the test of time and aluminium ticks all the boxes.

4. Lightweight and Manoeuvrable:

Aluminium's lightweight nature makes it a dream material for sign installations, lugging steel posts around a work site or positioning steel framework can require heavy machinery. Sign Trade Supplies recognises the ease with which aluminium can be handled and transported, allowing for quick and efficient installations. This characteristic not only simplifies the manufacturing process but also reduces logistical costs, making it an economically viable option for nationwide roll outs and project work.

5.Endless Possibilities:

Thanks to the above properties of aluminium, we think the sky is the limit when it comes to the sign design possibilities.


  1. Take tonnes of recycled scrap aluminium.
  2. Use renewable energy to cast it into a solid aluminium billet.
  3. Take the billet and extrude it into extrusions for sign posts, channel, trim, angle flat bar or anything you can design!
  4. Choose a finishing technology to improve durability and achieve aesthetic requirements.
  5. Convert the final material into a sign system that will be used for years to come!
