Water Transmission Mains Extend Much Broader Coverage
Municipal utilities increasingly specify PVC-M transmission mains that deliver large-diameter impact resistance standard PVC-U designs alone cannot support reliably across expanding trenchless applications, where sustained impact reliability matters more than the added unit cost engineered modified-PVC architecture introduces, with manufacturers such as Aliaxis Group SA expanding transmission main production capacity to meet rising specification demand across their growing utility customer base worldwide. Transmission main demand grows to about 19% of category revenue, and gross margins run 22% to 29% across the category. This trend continues accelerating through coming years across the global utility buyer base in particular.
