Packing and Delivery

We use wooden crates or pallet boxes for packaging.Each item is sealed in a VCI bag to prevent rust, then packed in sturdy hard boxes or crates designed to withstand stacking and handling. Larger parts are secured with stretch film to prevent shifting. All units are palletized for efficient forklift loading and optimized container space.
