Where it all started

Patt Projects is a family owned business and was started by Piet and Tina van der Merwe in January 1981. The company was first involved in the erection of steel structures. With the ever increasing demand of steel structures, the family then decided to start manufacturing there own steel structures.

This involved the cutting, welding etc of structures to clients specifications. Then came the in-house design office thus fulfilling the need for a comprehensive support in the manufacturing, designing, and erection of steel structures.

Our Projects


Our client requested a 15 x 30 Steel structure joined onto his existing structure, over their current shop. All work had to be done over a weekend to ensure customer client safety as well as uninterrupted trade.


Our client requested several different structures for storage and workshops. Which included but not only the spectator view point and walk way as seen in the images.


Our client requested 30 x 25 x 7 structure. This included Bullnoses and Alucushion to ensure a low inside temperature for his clientele as it is going to be a retail outlet.

Our Services


An aluminium coating can be applied to steel sheets. This coating consists of more or less 55% aluminium, 43,4% zinc and 1,6% silicon. This coating called Aluzinc is known for expanding the lifespan of our steel sheets by eliminating the rusting process and shielding your sheets against corrosive environments.

Aluzinc grants you multiple safety features and is a 100% chromium free surface treatment that shows that it is extremely environmentally friendly material that can and should be recycled to sustain our beautiful planet. We at Patt Projekte Steel Constructions have mastered the way to rig Aluzinc and make your building environmentally friendly and still leave a structure that can deliver peak performance while still being able to give a lasting building that will suit your every need.


Speed, efficiency and quality are three standards that we at Patt Projekte desire from our staff, to increase these attributes we have bought a plasma cutter that can perform delicate jobs with ease to reduce stress of our already hard working staff. 

Our state of the art laser cutter can cut through 16mm steel plates with ease

We provide plasma cutting services of any kind or shape to our clients.

We use this machine to develop many of the complicated components of the buildings that we rig at a fraction of the cost to suit the customer’s needs.


At Patt Projekte we constantly find new ways for our buildings to be even more environmentally friendly by applying cost effective ways to change the building to endorse our diplomacy towards our planet. We contemplate the best ways to save money on behalf of our clients, but avoid creating structures that could be harmful to the environment.

Why use Alucushion in your metal building?

  • It is a full vapour barrier that blocks interior moisture from getting to the panels
  • Very durable and cannot be ripped or torn by hand
  • Safe to handle and requires no special clothing or breathing equipment
  • Ideal insulation for metal frame building applications
  • Quick and easy to install
  • Reduces heat loss and heat gain all year round


Here at Patt Projekte we have Sketch artists that are using all of their constructing skills to create the most perfect sketches that are in the client’s best interests. Our sketch artists pride themselves on making a timeless structure via a 3D-Renderding program that will give you the ability to peak into the future and get an idea of what your structure will look like. It is also beneficial for any changes that can occur that can be estimated beforehand to increase the structure’s stance, environmental friendliness or just to improve the overall look.


What are Polycarb sheets?

Polycarb is made from a synthetic resin in which polymer units are linked by a carbonate group. Polycarb is highly praised for its transparency and its ability to be a natural UV filter. The sheets also possess incredible flexibility and strength. We at Patt Projekte provide these sheets at a decent price and fit them via our rigging crews.

Patt Projekte can provide any of these colours to our clients and apply it with expert precision. We also provide expert advice on colour schemes and the different properties that certain colours possess. The advantages and disadvantages are also made clear for the clients. Patt Projekte believes in applying a professional finish to the last stroke and leaving no detail half done.
