Complete concrete plants and custom steel solutions

Concrete Batching Plants

We deliver complete, turnkey batching plants for any project size, ensuring consistent quality and maximum uptime.

  • 30 m3/h & 60 m3/h capacity
    Precision-engineered to your site’s throughput requirements
  • PLC-controlled automation with fully programmable batching sequences
  • Gravimetric (weight-based) batching.
    Industry-leading accuracy for consistent mix performance
  • On-site buildup & commissioning – from foundations to final acceptance tests, we manage the entire build

Valves for Concrete Machinery

Our valves keep your material flow under total control – whether you need simple hand-operated gates or fully automated shut-off systems.

  • All standard sizes: 0.5m3, 1m3, 2m3 & 3m3
  • Manual, pneumatic & electric actuation
  • Custom adapter kits
  • High-performance sealing for abrasion-resistant materials

Concrete Accessories

Augment your plant’s capabilities with high-quality modules that slot seamlessly.

  • Precision-welded hoppers & feed chutes
  • High-frequency vibrators for compaction and de-aeration
  • Screw conveyors (augers) and modular attachment frames
  • Optional accessories: weigh-belt feeders, dust-control covers, level sensors

Silo Solutions

Keep your bulk materials dry, clean and ready for use with our silo discharge and filtration systems.

  • Manual & automatic discharge valves
  • Overpressure safety valves
  • Pulse-jet and cartridge filtration to trap fines and protect fans
  • Level monitoring & alarm systems integration

Spare Parts & Linings

When production can’t stop, count on our rapid-response parts service—matching or improving on your original components.

  • Electro-welded steel liners
  • Custom-made parts from client drawings or samples
  • One-to-one replicas of legacy valves, flanges, blades, etc.

Industrial Equipment & Custom Steel Fabrication

From floating pontoons to heavy-duty drive chains, our steel-workshop delivers robust equipment tailored to your needs.

  • Pontoons & concrete recyclers
  • Cold-formed high-strength frames and plasma-cut steel profiles
  • Heavy-duty chains, rollers, shafts, gears & bushings
  • Custom assemblies: brackets, skids, foundations, safety cages

Custom Fabrication to Your Specifications

Every project is different. We can produce a single prototype or handle larger runs. Give us your CAD files, sketches, or samples, and our workshop will make parts that match your specs.
