They comply with current regulations and are characterized by their safety and efficacy. By substituting concrete, they reduce environmental impact while offering great adaptability to both soft and rocky terrain. ### Key Advantages vs Concrete Foundations | Feature | Foundation Screw | Concrete Foundation | |---------|-----------------|-------------------| | Installation time | 1 day per MW | 3-5 days minimum per foundation | | Waste generated | Zero waste | Generates rubble and waste | | Reusability | 100% reusable and recyclable | Not reusable or recyclable | | Curing time | None, immediate use | 28 days curing required | | Total project cost | Lower total cost | Higher labor and material costs | | Reversibility | Fully reversible and dismountable | Permanent and irreversible | **Foundation screws reduce installation time by up to 70% compared to traditional concrete foundations.** ### Manufacturing Process Our manufacturing process is certified by ISO 9001:2015 and EN 1090-1:2009+A1:2011 standards. --- ## Ground Screw Models URL: https://www.tamsolar.com/ground-screw-modelos ### Model TPE - Screw with Point and Helix The most versatile screw, installable in any terrain. For earth to semi-solid soils, it can be screwed directly achieving excellent load values. It displaces surrounding earth during insertion and compresses it, using the spiral to grip the surrounding surface, with terrain cohesion determining its displacement point. ### Model TBE - Screw with Socket and Helix Designed for installation with pre-drilling. No point to reduce cost, but features a socket that facilitates introduction and pushes away stones that may obstruct the drilling hole. ### Model TPH - Screw with Point and Single Helix Suitable for soft terrain. Soft soils are often problematic for achieving desired resistance values, but this model achieves them. ### Head Types 1. **Hexagonal Head with Collars**: Perfect geometry - hexagonal shape distributes force uniformly when inserting the screw, with the smallest circumscribed perimeter, optimizing material use. 2. **Hexagonal Head with Central Nut**: Hexagonal shape with a central nut to fix the structure part without depending on screw position. 3. **Hexagonal Head with Welded U**: Central nut replaced by a welded piece that couples to the U profile of structure pillars. Position-dependent. 4. **Vertical Head**: The screw acts as a pillar and anchors directly to the structure crosspiece. Can save costs by eliminating intermediate pieces. ### Point Types 1. **Extended Point** (400mm length): Formed directly from the steel tube. Achieves smooth and constant penetration, capable of pushing aside small stones. Most versatile and resistant point on the market. 2. **Conical Point**: Specially designed for helix screws. For very soft terrain where placing the helix as deep as possible is the main objective. 3. **Socket Point**: For pre-drilled installations. Provides proper centering of the screw in the hole and pushes aside stones that may obstruct advancement. --- ## Applications URL: https://www.tamsolar.com/ground-screw-aplicaciones Foundation screws open a universe of possibilities in design, efficiency, and adaptability. Regardless of terrain nature or project type, these screws provide a solid and safe foundation. ### Photovoltaic Structure Anchoring From the scorching deserts of Dubai and Atacama to the plains of Brazil and the green meadows of the United Kingdom, through the sands of the Tagus estuary and the imposing Alps mountains - our ground anchor screws are designed to adapt to an incredible diversity of terrain and soils, providing a safe and reliable base for photovoltaic plant installation anywhere in the world. ### House Foundation Ground anchor screws offer a practical and resistant solution for house foundations, especially single-story homes. This system is widely used for creating a cantilevered sanitary slab, providing a solid and durable base. ### Awning and Tent Anchoring Fixing awnings and tents is a simple and clean process thanks to ground anchor screws. Eliminates the need for concrete and heavy machinery for drilling - just install the screw for solid and instant attachment. ### Parking Structures Foundation screws are ideal for parking construction. Quick and effective installation allows secure fixing of parking structures, facilitating construction and guaranteeing structural durability. --- ## Solar Panel Structures URL: https://www.tamsolar.com/solar-panel-structure TAM manufactures solar panel structures offering high-quality solutions that ensure maximum efficiency and durability of photovoltaic systems.

Foundation screws are steel anchors that screw directly into the ground to serve as foundations for solar panel structures. They replace traditional concrete foundations, offering faster installation, lower cost, and zero environmental impact. TAM manufactures them since 1992 at its plant in Ontinyent, Valencia. ### What advantages do foundation screws have over concrete? Foundation screws reduce installation time by up to 70%: one day per MW versus 3-5 days for concrete. They generate zero waste, are 100% reusable and recyclable, require no curing time, and are completely reversible. The total project cost is lower because they eliminate excavation, formwork, and concrete pouring. ### In which countries does TAM Industrial Energy operate? TAM has completed over 1000 projects in more than 18 countries across Europe and Latin America, including Spain, Portugal, France, United Kingdom, Germany, Italy, Netherlands, Greece, Turkey, and countries in South America. Our manufacturing headquarters is in Ontinyent, Valencia, and we export worldwide. ### What is a POT test and why is it important? POT (Pull Out Test) is a field test measuring the extraction resistance of a screw installed in the actual project terrain. It is essential to validate that the chosen foundation model supports the required loads. TAM performs POT with proprietary machinery capable of drilling, screwing, and testing with a single machine on site. ### Does TAM manufacture its own screws? Yes, TAM Industrial Energy is a manufacturer, not a distributor. We design and manufacture our foundation screws in our own facilities in Ontinyent, Valencia, with 8 specialized machines. Our process is certified under ISO 9001:2015 and EN 1090-1:2009+A1:2011, controlling quality from design to field installation. --- ## Contact URL: https://www.tamsolar.com/contacto - **Address**: Carrer Del Tint 6, Ontinyent, Valencia 46870, Spain - **Phone**: +34 96 291 60 96 - **Email**: esanchis@tamsl.com - **Business Hours**: Monday to Friday, 08:00 - 18:00 - **Languages**: Spanish, English, French, Portuguese Contact form available on the website for project inquiries and quotes. --- ## Legal - [Privacy Policy](https://www.tamsolar.com/terms-of-service/politica-de-privacidad) - [Cookie Policy](https://www.tamsolar.com/terms-of-service/politica-de-cookies) - [Legal Notice](https://www.tamsolar.com/terms-of-service/aviso-legal) - [Quality Policy](https://www.tamsolar.com/terms-of-service/politica-de-calidad)
