PHOENIX, Ill. — Sterling Structural, a leading manufacturer of cost-effective, pre-fabricated mass timber and hybrid structural systems in North America, announced a modular Shaft Wall System for new construction. The system supports all major elevator manufacturers or egress stair designs and enables builders to save time and cost from elevator wall shafts without sacrificing fire safety or structural integrity, all while reducing embodied carbon compared to concrete or masonry shaft walls. The new system features pre-fabricated Cross-Laminated Timber (CLT) panels for shaft walls—and, in some cases, roofs—along with coordinated connection details and all necessary hardware. Sterling’s project management team coordinates deliveries, sequencing panels for easy installation, whether the project uses platform or balloon framing.
