Speedy construction! Of course, we can create perfectly round dome ceilings, as well as oval-shaped dome ceilings. Based on the assembly diagram, you can construct the base with a model kit feel!

The "K1 Free Dome System" is a lightweight steel frame ceiling substrate construction method that accommodates three-dimensional curved ceilings (dome ceilings, reverse dome ceilings). Small-scale dome ceilings can be manufactured and assembled at our factory before shipping. For larger scales, components processed with R-curvature can be delivered in a knockdown (on-site assembly) format. 【Features】 1. Wide range of design compatibility Not only can we create perfectly round dome ceilings, but we can also produce elliptical dome ceilings. We also accommodate three-dimensional curved walls. 2. Speedy construction Based on assembly drawings, the substrate can be assembled with a model kit-like feel. 3. Outstanding precision Compared to traditional site-welded assemblies using square pipe R-processed products, the precision of the K1 Free Dome System is incomparable. We also have a track record with screens for planetariums and similar applications. - Speedy construction without welding - Reliable precision - No need for molds required for G.R.C / G.R.G / F.R.P / gypsum, etc. - Production of substrate for indirect lighting associated with dome ceilings is also possible. *For more details, please refer to the PDF document or feel free to contact us.
