Your Solution to Complex Challenges

With over 40 years of expertise, Alternative Structures is a leading specialist in metal pressings and plastics, catering to design, development, and manufacturing needs. Our commitment extends beyond these fields as we take pride in being the industry leader in delivering top-notch forestry equipment and reliable mechanical measuring instruments, ensuring superior quality for all your application requirements.

Measuring Instruments

Our comprehensive selection of forestry instruments and equipment ensures that foresters have access to the highest quality tools they need for precise measurements. From tree measuring devices to forest mapping equipment, our offerings are tailored to meet the unique requirements of forestry professionals.


Metal Pressings

We have been the leading supplier and designer of premium metal plates to South Africa's treated pole industry. Since 1993, our unwavering commitment to excellence has made us the trusted choice for pole treaters, thatchers, hardware stores, and customers in the building industry.



With over 40 years of experience, we have garnered extensive expertise in various plastic manufacturing processes. At present, our primary focus lies in the utilization of injection molding techniques for the majority of our production. Our wealth of knowledge and proficiency in this field enables us to deliver exceptional plastic solutions that meet the highest standards of quality and precision.


Design and Development

To maintain our core expertise, we follow a strategic approach of designing products and creating tooling according to our own specifications. We then establish long-term partnerships by subcontracting the manufacturing process to trusted and reliable manufacturers. We ensure that our products are produced with precision and adherence to our strict quality standards while allowing us to focus on our core strengths in design and specifications.

Every project is important to us

At Alternative Structures, our ambition is to be recognized as global leaders in our industry. As a company, we firmly believe in upholding the values of excellent service, honesty, and loyalty to both our esteemed customers and valued suppliers.

Signumat Protectors

The protectors represent a simple and ecologically worthwhile measure not only against game browsing, buck rubs and birds, but also against the formation of tree forks. This is possible due to the appropriate geometry and the high-quality, technical plastic. With the stable, tried and tested snap-fastener, the protectors offer a time-effective protection for both – soft- and hardwood. In addition to the UV-resistance of the colors, there is another benefit: the blue color has a deterrent effect on game. The protectors should be placed on the terminal shoot between September and March. Then, a year-round protection is guaranteed. 


The EasyClip was developed – and is proudly manufactured – in South Africa. There was a need for a tough, cost-effective fastening system that saves installation time and allows for easy maintenance while still providing a high-quality finish that extends the lifetime and improves the aesthetics of any hardwood timber or composite deck.


Our products serve a multitude of purposes, with a particular emphasis on forestry applications. However, their versatility extends well beyond the forest industry, finding relevance and providing effective solutions in various other fields. From construction and building projects to agricultural endeavors and beyond, our products offer versatile solutions that cater to diverse needs outside the realm of forestry. With their adaptability and superior quality, our offerings have become trusted solutions across multiple industries, demonstrating their effectiveness and value in meeting a wide range of requirements.


The Signumat system helps you improve both organization and accuracy of stock control.

Made from top quality plastics and materials our products are durable, easy to apply and will save you time! Signumat products have proven quality, don't be fooled by imitations.
