Mesh, perforated and expanded metals featured in Metal Architecture’s June 2020 issue.
GKD Metal Fabrics
GKD offers all of its metal fabric in the Bronze collection. The Bronze collection can be clear coated to retain a bronze tone or left unfinished so a patina will develop. GKD also offers five new metal fabric weaves: Choptank weave, Ellipse 52 aluminum weave, Helix 36 aluminum weave, Ripple weave and Tigris TC-3 weave. Choptank is a dimensional square weave pattern with small open area. Ellipse 52 has tight dimension, Helix 36 is lightweight and Ripple looks like ripples on water. Tigris TC-3 has a triplet of warp wires spaced along a straight weft and woven along a crimped horizontal wire.
