Carlos Metal Building Material receives its high reputation due to round seam packet column. Carlos Metal Building Material's metal ceiling panels series are created based on unremitting efforts. Carlos round seam packet column is developed by our professional R&D team, based on application scenarios and usage characteristics in the market. The product is focused to overcome the shortcomings among similar products. A list of certifications like SGS can guarantee the quality of our products. The product has no extra loose thread appearing along the seam. Post sewing, all the threads will be carefully trimmed using clippers or trimmers by workers. Our different aluminum panels can meet different requirements of our customers.
