Pre-embedded channels are prefabricated components used in construction, where a C-shaped channel is first embedded in concrete, followed by inserting the head of a T-bolt into the C-shaped channel. The components to be installed are then secured with the T-bolt. The quality characteristics of pre-embedded channel steel include: high load-bearing capacity, up to 32kN or 128kN/m; narrow side margins, as small as 5cm; easy adjustment; noiseless and dust-free installation; official certification obtained; suitable for both static and dynamic loads; excellent corrosion resistance, made from stainless steel or hot-dip galvanized steel. These comprehensive quality features make pre-embedded channel steel an indispensable product for all designers and users.
