Sometimes building design professionals struggle with specifying materials. First of all, the CSI (Construction Specifications Institute) format for building product specifications is geared toward systems, not materials. This tends to favor delegating the responsibility for material selection to the panel manufacturer or fabricator in the case of metal building panel systems. 

Although system providers can be capable of making good decisions, the architect’s vision and the building owner’s best interests are reinforced when clear and specific instructions are given regarding the materials to be used.

In the case of building envelope materials, the impact of material specifications is particularly high in terms of visual appearance and cost to the owner. The material chosen plays a substantial role in how the building looks and what it costs to operate in the long term. Contrarian Metal Resources produces and distributes high performance metals that balance visual excellence with true sustainability. Whether the application is interior or exterior, design professionals often agree that our products are worthy of specification.
