Detailed Service Description
We provide professional precision assembly service for heavy steel structure parts, aiming at prefabricated steel structure building projects, realizing factory-based integrated assembly of scattered steel components, replacing traditional on-site welding & assembly, greatly improving construction efficiency and component quality. For large-size, heavy-weight steel structural parts, we adopt professional tooling clamping and precision positioning technology to ensure the matching accuracy between components.
The whole assembly process is carried out in a standardized factory workshop, avoiding the impact of outdoor weather, site environment on assembly accuracy and product quality. We carry out pre-assembly, fine adjustment, full positioning welding and overall calibration for all heavy steel parts, ensuring seamless butt joint of components and zero deviation of mounting holes, which can greatly reduce on-site construction difficulty, shorten construction period and lower labor & installation costs.
We have professional large-scale assembly fixtures and lifting equipment, capable of handling super-large and heavy steel structure assemblies, supporting integrated assembly of steel frame, support members, connecting parts and other accessories. After assembly, we conduct overall dimensional inspection, verticality detection and firmness test, and carry out unified surface anti-corrosion treatment, delivering finished assemblies that can be directly hoisted and installed on site.
