Family-Built.
Field-Proven.
Since 1998, Sieruta has engineered attachments that don't quit. Precision manufacturing for operators who demand zero excuses.
"We don't just sell steel. We sell zero downtime."
It started in a small workshop in Ostrołęka with a simple belief: heavy machinery deserves attachments that match its durability. We saw too many buckets failing and too many couplers cracking under pressure.
Since 1998, we have remained family-owned and fiercely independent. This allows us to prioritize quality over quarterly profits. Every weld is inspected by eyes that care about the family name stamped on the side.

Zero Compromise

You deserve to know what you're buying. We provide full steel traceability on every attachment, so you know exactly what grade of metal is doing the work.
