In the large-scale production of steel structures, the batch descaling of structural steel and steel plates—characterized by low efficiency, high labor costs, poor coating adhesion, and persistently high rework rates—has long stood as a crit00ical bottleneck constraining both production capacity and product quality. As a leading enterprise in China's steel structure industry, Hangxiao Steel Structure was in urgent need of an efficient, stable, and cost-effective surface pretreatment solution.
Leveraging its deep technical expertise and extensive industry experience, Qingdao KEEJOO Group became a strategic partner to Hangxiao Steel Structure. By providing a customized solution featuring roller conveyor shot blasting machines—with a cumulative supply of 245 units—KEEJOO has successfully equipped all of Hangxiao Steel Structure's production bases.
Addressing the critical pain points associated with the batch descaling of structural steel and steel plates, the KEEJOO Brand roller conveyor shot blasting machine utilizes a modular design and precision shot-blasting control technology to achieve highly efficient descaling and standardized surface pretreatment for large-scale components. The equipment delivers remarkable results once operational. Enhanced Quality, Drastically Reduced Rework Rate: Rust removal standards consistently meet the Sa2.5 grade; coating adhesion has improved by a direct 30%, completely eliminating the risk of coating detachment. With the rework rate driven down to below 1%, product quality has achieved a qualitative leap forward.
Doubled Efficiency, Drastically Reduced Labor Costs: Leveraging an automated continuous-operation mode, single-shift throughput has increased fivefold. By moving beyond the inefficiencies of traditional manual polishing, labor costs have been slashed by 80%, resulting in a significant boost in production capacity. Hassle-Free Operations, Halved Downtime: Featuring a modular structural design paired with maintenance-free core components, the equipment boasts a significantly reduced failure rate. Maintenance-related downtime is cut by 60%, ensuring continuous and stable 24-hour operation of the production line while substantially lowering overall operating costs.
From rust removal quality to production efficiency, and from labor costs to operational support, KEEJOO Brand roller conveyor shot blasting machines comprehensively address the critical pain points facing the steel structure industry, establishing themselves as the benchmark choice for the efficient rust removal and pretreatment of large-scale steel structural components. Moving forward, Qingdao KEEJOO Brand will continue to empower the steel structure industry through innovative technology, assisting more enterprises in achieving the dual objectives of cost reduction and efficiency enhancement, alongside quality improvement.
