All of our products are made to order. Standard fabrication time of most items is 6-8 weeks after the order is placed, and does not include shipping time. Estimated standard lead times are not guaranteed, and do not apply to custom or high volume orders. For lead times on special orders or for large quantities, we will contact you directly. If you paid for expedited fabrication, your order will be ready to ship in 2-3 weeks, guaranteed. If your expedited items have not shipped after 3 weeks, the 25% rush charge will be refunded. Please note that some products and finishes are not available for expedited fabrication and require longer lead times.
We offer refunds on most unused merchandise minus a 25% restocking fee, excluding any shipping and handling costs. Accurate locks and Baton cyclinders are non-returnable. Items must be returned within 15 days of delivery in new condition and original packaging. Any damages that occurred during shipping must be reported within 5 days of delivery for a proper replacement or credit to be given. Large volume orders, and some bronze items, may not be eligible for return. We are not able to offer refunds on custom orders.
Our products are fabricated and finished by hand; variations in size, shape, and patina color are a natural result of this process. Tooling marks and surface scratches are part of the character of many finished pieces. In particular, Tom Kundig’s Black series of folded steel tables, shelves, and desk have pronounced tool marks from the process of bending the steel, and variations in surface texture and color are part of the intrinsic nature of steel plate.
Our blackened steel and bronze products are sealed with oil and wax, which over time are not impervious to moisture. These finishes allow the metals to age naturally and develop their own character and patina through time and through use. They are essentially “live” finishes that breathe. Our blackened steel pieces installed outside, or in areas exposed to moisture indoors, especially in marine environments, will rust. Condensation from hot and cold drinks will leave rings on blackened steel table tops. Coasters or placemats can protect the finish. For a more durable exterior finish, or for interior kitchen and bath areas, we recommend the stainless steel, bronze, or powder coated steel finishes (if available). Steel hardware should not be installed with dissimilar metals; this may initiate galvanic action, and accelerate corrosion of the steel.
Periodic maintenance of blackened steel items may be required. For light cleaning, they can be wiped with a slightly damp rag, and buffed immediately with a dry cloth. Never use bleach, ammonia, or other aggressive household cleansers. Something very mild like diluted Dawn dishwashing liquid is OK. To maintain the original luster, the wax finish can be refreshed with a light application of Trewax or a similar carnauba paste wax, perhaps every six months or so, depending on location and level of use. For treatment of minor corrosion or surface rust, we recommend rubbing the affected area lightly with very fine Scotch Brite, and re-sealing with a lightly buffed coating of carnauba paste wax. Used aggressively, Scotch Brite or other abrasives may scratch or remove some of the blackened patina under the wax.
