Tapered Rectangular Conical Structure

Shin Seoncheong, South Korea – Tapered Rectangular Chimney

Global Chimneys Co. Ltd. hired Gleitbau GmbH of Salzburg Austria, to slipform this new chimney structure. The sliding operation was performed during 2017. The tapered rectangular shape makes for a unique and spectacular tower-like structure, made possible by the latest advances in slipform technology. The overall height is 148 m and the base dimensions of 20 m x 20 m taper off to 12 m x 12 m at the top. The wall thickness reduces from 0.90 m at the bottom to 0.35 m at the top.
