How do I order custom-made products?

Send your new product drawings or samples to us. We can custom-make hardware according to your requirements and provide professional advice to maximize performance.

What is the recommended transport mode?

Since production items are generally heavy, we advise delivery by sea. However, we respect your views on other transportation methods as well.

What if I cannot find the product on your website?

You can send pictures, photos, or drawings via email. We will check if we have them. If not, we develop new models every month or can create a special model based on samples sent via DHL/TNT.
