Unlike traditional hot-rolled profiles, the Plate Welded Steel Components manufactured by Guojian suppliers are not limited by fixed specifications. Their height, width, plate thickness, or structural form can be freely customized according to project drawings. This design was developed specifically to address the challenges faced by large-span, high-load, irregular or super-large steel structure projects, and has become the core load-bearing components in high-rise building infrastructure, heavy industrial equipment installation, large venues, and large-scale new energy projects.
1. Fully customized specifications – breaking free from the limitations of national standards
2. Strong load-bearing capacity and more stable overall structure
3. Fully automatic welding process – reliable weld seam quality
4. Precision cosmetic correction – high flatness
5. Multi-layer corrosion protection technology – extended service life
6. Integrated deep processing – reducing customer costs
1. Concerns regarding poor welding quality or hidden defects in non-standard components
Our factory offers fully automated welding combined with 100% non-destructive testing sampling, and issues official inspection reports – ensuring hassle-free project acceptance.
2. Concerns regarding excessive board thickness variation, intentional thinning, or falsely inflated bearing capacity
All sheets are genuine, medium-thickness steel plates conforming to Chinese national standards; their actual thickness is measured, they can be weighed, and third-party re-inspection is available, ensuring that the structural loads fully comply with the specified requirements.
3. Concerns regarding significant welding deformation or misalignment during installation
Professional welders ensure minimal Plate Welded Steel Component deformation and high dimensional accuracy, eliminating the need for secondary adjustments during on-site installation.
4. Concerns about rusting and short lifespan when used outdoors
The appropriate corrosion protection grade can be selected based on the project's geographical location and operating conditions, effectively addressing corrosion issues encountered in coastal, rainy, or sun-exposed environments.
5. Concerns about prolonged project timelines and delays in customized delivery
Factory assembly line operations feature rapid production scheduling and stable project timelines, allowing priority production for urgent orders and ensuring the timely completion of key project milestones.

A: Hot-rolled steel sections come in fixed standard specifications, making them suitable for conventional secondary structures, purlins, and standard frames; Plate Welded Steel Component are custom-made on demand, capable of accommodating ultra-thick, oversized, or non-standard cross-sections, offering enhanced load-bearing capacity – specifically designed for primary load-bearing structures, large-span applications, and heavy-duty core structures.
A: For general indoor applications, use a rust-preventive primer; for outdoor applications, use an epoxy zinc-rich primer followed by an outdoor topcoat; for coastal areas with high corrosion exposure or photovoltaic outdoor projects, hot-dip galvanizing or heavy-duty anticorrosive coating is recommended for longer service life.
