Frequently Asked Questions

What is this product best used for?

It is built for high-use environments — commercial gyms, fitness studios and other facilities where equipment is trained on every day. It also suits private training studios and corporate or hotel fitness rooms when the training load is lighter.

Our standard production lead time is 30 days after order confirmation and receipt of deposit. If you have an urgent requirement, contact us to check whether an expedited schedule is possible for your order.

What is your minimum order quantity (MOQ)?

MOQ depends on the product and the level of customisation required. For standard catalogue items our minimums follow common wholesale practice for gym equipment. Send us your product list and target quantity, and we will confirm the exact MOQ for your order.

Is your factory audited for social compliance?

Yes. Our factory holds amfori BSCI certification (monitoring ID 22-0143442-1). BSCI is a widely recognised social compliance audit, and many European and international buyers require it or an equivalent audit before onboarding a supplier.

We are happy to supply the technical documentation and test data needed for that process.
