Packing & Delivery

Bulk/Fiber Bag/Neutral packing

Carton/Box

Wood Pallet/Box

Bagged packaging is ideal for smaller quantities of fasteners. The fasteners are placed in durable plastic bags, which are then sealed to protect the contents from moisture and dust. Each bag is clearly labeled with product details and quantities. This packaging is easy to handle and transport for smaller orders, making it convenient for workshops and retail settings.

Boxed packaging offers a more structured solution for medium to large quantities of fasteners. The fasteners are packed in sturdy cardboard boxes, which provide additional protection against physical damage during transit. The boxes are designed to stack neatly, optimizing storage space. Each box is labeled with essential information, ensuring easy identification and inventory 

Palletized packaging is used for bulk shipments of fasteners. Multiple boxes or bags are securely strapped onto a pallet, creating a stable and easily transportable unit. This method is highly efficient for large-scale distribution and warehousing. Palletized packaging ensures that large quantities of fasteners can be moved quickly and safely using forklifts, reducing handling time and labor costs.
