Industrial Steel Liner Panels Guide: MOD-36, Q900 & Corrugated Wall Liners

Introduction: Hiding the Skeleton

Exposed structural steel and bare fiberglass insulation look terrible. Dust collects on the purlins. Forklifts accidentally tear the vapor barrier. You must lock the structural skeleton behind interior wall panel systems. As a specialized B2B cladding supplier, we source precision interior skins from verified OEM factories. Do not guess the profiles. Here is the absolute engineering matrix for industrial interior liners.

1. The 0.37mm High-Reflectance Steel Standard

Interior panels do not fight rain. But they fight humidity and impacts. We mandate 0.37mm high-reflectance pre-painted steel. It features an AZ70 Zincalume coating. The interior face receives a premium 12μm white polyester finish. This creates a brilliant, hygienic warehouse interior lining. The bright white surface reflects factory lighting perfectly, slashing your monthly electricity bills.

2. Placement Mechanics: Above vs. Below Purlins

The structural orientation changes everything.

• Above the Purlins: The mod 36 roof and wall liner sheet sits directly on top of the roof purlins. It acts as the structural steel deck to carry the uncompressed double-layer TMR insulation system.

• Below the Purlins: The q900 under purlin steel ceiling panel mounts to the bottom flange of the purlins. It completely hides the steel framing, creating a smooth, uninterrupted ceiling plane.
