Why work with us
Real specifications
Weights, capacities and tolerances are measured, not copied from a supplier PDF. If a figure is approximate, it says so.
One person, start to finish
The same person quotes, inspects and ships. Nothing is handed to a call centre.
Small orders accepted
Most lines start at 10–50 pieces. We would rather grow with a customer than chase one large order.
Written before spoken
Prices, lead times and defect terms are confirmed in writing before any payment.
