To meet the European Environment Friendly Standard, and our customers artistic requirement of frames, SEK adopts two ways to color the frames, namely Coated Powder Frames and Anodic Oxidation Frames.The frames are further processed with anodic coloration and powder coloration.

1.Anodic Oxidation Frames

Anodic Oxidation is a kind of electrochemical oxidation of metal or alloy . We use aluminium alloy as the anode, by electrolysis to make its surface covered with oxide film.Thus, the oxide film changes the aluminium alloy’s surface condition and performance, such as color, at the same time improve the corrosion resistance and increase durable attrition.

Features of Anodic Oxidation Frame:
Different Solvent-resistant, Corrosion-resistant, Lasting color, Durable attrition.

2.Sandblast Frames

SEK adopts the Sandblast Technics on stretching side of frames to ensure the surface of the frames are abrasive enough to guarantee 100% adhesion.
