An employee uses a remote control to oversee the precise assembly of a massive yellow steel component. The striking difference in size between the person and the massive structure highlights the impressive scale of production at Stapu.

Counterweightsfor three generations

Since our founding in 1972, we have grown from a supplier to the construction machinery industry into one of the leading manufacturers of counterweights. We specialize in large dimensions, enabling us to produce counterweights of up to 63 tons and other steel structures of up to 23 tons. Our product portfolio includes:

A solid yellow counterweight for construction machinery, mounted on a transport frame and a wooden pallet. An example of heavy-duty steelwork by Stapu for the construction machinery industry.
  • Counterweights
  • Welded structures for diesel and hydraulic tanks
  • Machine housing components
  • Base plates

Of course, we are also open to inquiries regarding steel components for other applications. For more information on ­our technical capabilities and the dimensions we can produce, please visit our menu item “Steelwork”.

Stapu is a medium-sized, family-run company with approximately 250 employees at 4 locations in Europe, supplying customers from all over the world with complex welded components. For us, the highest product­quality and customer­satisfaction are our top priorities. That is why we offer our customers comprehensive consulting even before the project begins and, upon request, create complete sets of drawings for steel components weighing up to 23 tons per piece. We always take full responsibility for quality and on-time delivery and, in return, offer exceptional logistics services through comprehensive organization, the preparation of customs documents, shipping documents, and certificates, scheduling, and shipping.

To meet these high quality standards, we need a strong and highly qualified team. That is why our employees—from production and quality assurance to logistics —receive ongoing training and professional development. To this end, for example, we have established a training center at our location in Romania and founded a quality assurance company in China.
The ongoing training of our employees and continuous inspections not only ensure the quality of our products, but also contribute significantly to workplace safety and thus to the protection of our employees—another important cornerstone of our corporate philosophy.

Environmental protection is also part of our corporate philosophy. Through further developments and adjustments, we strive to minimize our environmental impact as much as possible and thus commit ourselves to the sustainable protection of our habitat.
