NAAMS Stack Risers

NAAMS stack risers are made out of ASTM A-36 steel. They come in as short as 150mm with the ASR115 and go up to 800mm with the ASR280. ASR115 to ASR150 stack risers are manufactured with a base of 195mm length and 170mm width coming in at 20mm thick. The riser plate is 15mm thick with a 140mm length and 110mm width. The NAAMS standards height for these risers starts at 150mm with 50mm increments to 500mm.

ASR240 and ASR280 stack risers are used as a base riser for ASR115 to ASR150. They feature a wider base and riser plate with the base being 215mm long and 190mm wide. The riser plate is increased to 195mm long and 170mm wide.
