Metal Formwork in Civil Construction: Everything You Need to Know!
In civil construction, every detail directly impacts the project’s deadline, cost, and quality. When it comes to forming structures with precision and safety, metal formwork emerges as an intelligent solution, especially when combined with technology, technical support, and productivity.
In this Q&A format, we answer the most common questions about SH metal formwork systems. From materials to compatibility with self-compacting concrete, from choosing the ideal model to the difference between Concreform®SH and Tekko®SH, here you’ll find practical information to help you make more informed decisions on your project.
What are metal forms for concrete?
Metal forms are reusable systems made of steel or aluminum panels used to mold concrete until it cures. They offer greater strength, productivity, and safety compared to wood forms, in addition to providing an excellent finish.
What are metal formwork used for in concrete structures?
These systems play an essential role in construction: they mold and contain fresh concrete, support loads until curing, and ensure alignment and stability. They also promote productivity and safety on the job site with a quality finish.
What types of metal formwork does SH offer?
SH offers a variety of solutions for different needs:
Concreform® SH: Ideal for walls, pillars, and beams, made of galvanized steel with 15 mm plastic-coated plywood. Available for rental.
Tekko® SH: Suitable for pillars, walls, and blocks, with steel panels and 12 mm plastic-coated plywood. Also available for rental.
Topec® SH: Used for flat slabs, made of aluminum with 10 mm plywood or polypropylene with fiberglass. Available for rental.
Lumiform® SH: Extruded aluminum system for slabs, walls, and beams. Complete aluminum structure and sold exclusively.
Multiform SH®: A versatile formwork system for walls, pillars, tunnels, bridges, and complex structures. Composed of MF-12 (double U) profiles and SH20 beams fixed with clamps, it allows for assembly in various geometries and supports loads of 60 to 90 kN/m², optimizing productivity on construction sites.
How does SH metal formwork rental work?
We offer a complete service: customized executive design, material delivery, field technical support, and strategic equipment relocation. All this to ensure agility, efficiency, and savings on your project.
Can the Lumiform® SH metal formwork system be used on any project?
Yes. It is quite versatile, but especially advantageous on projects with repetitive paving, such as residential and commercial buildings.
Are SH metal forms compatible with self-compacting concrete?
Yes, as long as they are correctly sized to withstand the hydrostatic pressure of this type of concrete and the application guidelines (concreting speed, height, and projection) are followed.
Do the metal forms come with plywood?
Yes. Each system has a specific type:
Concreform® SH: 15 mm plastic-coated plywood;
Tekko® SH: 12 mm plastic-coated plywood;
Topec® SH: 10 mm plywood or fiberglass-backed polypropylene board.
Is it necessary to apply release agent to the metal forms?
Yes. Using release agent facilitates release and preserves the plywood. For plywood forms, a mineral oil-based release agent can be used; for aluminum forms, vegetable ester-based products are recommended.
Can SH metal panels be drilled?
We do not recommend it. Our panels come with standard factory holes. Additional holes may compromise system performance.
Is it possible to obtain a visible finish with SH metal formwork?
Yes. It is sufficient that the panel layout and layout meet the aesthetic requirements of the architectural project.
What is the difference between Concreform®SH and Tekko®SH?
Concreform®SH is recommended for larger structures and supports up to 60 kN/m², with larger panels. Tekko®SH is ideal for columns, blocks, and various geometries, supporting up to 40 kN/m² and being more versatile due to its smaller panels.
What is the productivity of SH metal formwork systems?
The systems offer high productivity:
Concreform®SH and Topec®SH: 0.30 hh/m²;
Tekko®SH: 0.50 hh/m².
Are metal forms more expensive than wooden ones?
The initial investment is higher, but the medium-term cost-benefit is worth it. They are reusable, durable, and optimize construction time.
How can I avoid compensation when renting metal forms?
SH provides in-person training and guidance on equipment use and maintenance, minimizing losses and costs.
Does SH provide technical training and detailed design for metal form projects?
Yes. Our technical team monitors the project with visits and guidance on equipment assembly and maintenance. We also prepare
