PRODUCT CATALOG / TC-SERIES
Four core product lines covering standard, veneer, and exterior applications. All products manufactured to ANSI/WDMA I.S.1A and AWI quality standards.
TC-SHC
Standard Series
General-purpose hollow core for commercial and residential door manufacturing. Designed to be used with 1/4" shop sawn veneers on both sides of the core.
The TC-SHC is TorsionCore's baseline hollow door core — engineered for consistent cell geometry, tight dimensional tolerances, and reliable face bonding across high-volume production runs. Available in 1-3/4" and 2-1/4" nominal thicknesses.
