Full Steel Surface Treatment Line — Blasting, Painting & Drying in One Pass | ATHI QAT3720

Blasting in one bay, painting in another, curing somewhere else — every handoff is a part waiting, a surface picking up flash rust, a coating going on over an inconsistent profile. The result shows up later as rework and rejected batches. The QAT3720 was built to close those gaps. ATHI delivered this full pass-through line to a steel fabrication facility in Changzhou, where a part now enters as raw steel and leaves coated and cured — blasting, dust recovery, dry painting, and heat curing on one continuous cycle. No re-handling between stations, no waiting, no surface drift. What that means in practice: a clean, repeatable surface profile on every part, large workpieces handled without breaking them out of the line, emissions and dust kept inside compliance, and a throughput rate the shop can actually plan production around. This walkthrough follows a workpiece through the complete line, from the blast cabin to the finished coating coming out of the oven. ATHI (Qingdao AnTai Heavy Industry) builds turnkey surface preparation and finishing lines for steel structures, plate, profiles, and heavy fabrications — designed around the customer's parts, plant layout, and throughput targets. Built to ISO 9001:2015 certified | CE conformant | SGS verified standards. Request a line proposal for your own parts and plant: [email protected] · athi-group.com · WhatsApp / Tel +852 5427 1642
