Decades of experience shipping our products worldwide has given us the expertise to ensure that our products arrive to their final destinations intact. We’ve developed a 4 point system to prevent any damage during the various stages of the manufacturing process and shipping:
1) A protective film covering the surface of aluminum profiles.
2) Specialized cardboard encapsulating the window surfaces and corners
3) Plastic stretch wrap covering the glass.
4) Windows and placed within a non-fumigated ply-wood crate
We can handle freight and customs clearance through our shipping partner and can provide door-to-door service if desired. We guarantee that our clients will receive their orders timely and without damage.
