Props are the starting point in every multi-storey building construction. They are generally classified into: light props, DIN EN 1065 props, push-pull props, forked props, aluminium props and loading towers.

Besides helping you save materials and time, these props are a safe bet to achieve your results at the worksite.

We - at GBM - have been in the props manufacturing industry for more than 60 years.

Ever groundbreakers, since back when we were just small-scale manufactures up to today when we utilise the most advanced metal and finished product machining techniques, ever striving to achieve top-notch production.

Our props meet all quality standards required by the most demanding standards worldwide, throughout the entire manufacturing process.

Furthermore they are compatible with the most famous and widespread formwork systems, such as Dokadek 30, Dokaflex, Skydeck, Framax, Rasto-Takko, and many more.

Here is why our production process is unique:

• our products are made of quality raw materials, procured from painstakingly selected suppliers;
• we care about their durability and resistance over time and against harsh conditions, coating them with utmost protection (hot-dip galvanization in compliance with the UNI EN ISO 1461 standard)
• we meet safety conditions by providing anti-shearing and anti-slip-off systems.

However, manufacturing top-quality and supreme durability props is just the starting point to us: our experience alongside those working on the ground in any international market, has led us to diversifying our production into six different types of products striving towards meeting any demand.

GBM products are sold all over the world. Thus, each and every product must comply with safety and reliability standards always exceeding the standards required in the country of use.

Setting up a safe construction site requires compliance with strict standards. Right from the choice of materials used for setting up the worksite. This is why we - at GBM - make our products in compliance with strict quality standards: to guarantee safety and reliability for our customers. And for the customers of our customers.

Basically, here are the steps for manufacturing a certified GBM prop.

PROJECT — It all starts with our customer's needs. Whether you are a dealer in building materials on the other corner of the globe, or a major constructor striving to complete a large project, or a small-scale construction company, the first step always lies in identifying which products you actually need.

CUTTING — Steel pipes (both external and internal) are then cut to size with a +/-1 mm tolerance. Cutting is done using automatic cutting machines: a bundle of pipes is placed on the loader which selects one pipe at a time. It is then loaded on a positioning device and cut precisely at the desired height. Lastly, the pipe is unloaded into a container for the subsequent step.

WELDING — External pipes proceed to the welding step, where - suitably positioned - they are assembled with the base plate (previously forged by 250-ton press machines) and the end is threaded (obtained through a rolling-forming process, which reinforces its structure). Once drilled, the internal pipes undergo the same welding process but concerning the plate only.

FINISH — Depending on the product, next come the completion steps including: mounting an outer sleeve on the covered threading or a forged steel ring nut on which the product identification code is stamped; marking the plates with the customer’s identification code.

CAPACITY TEST — We perform in-house tests (capacity tests) on randomly collected samples.
