FAQs

What types of products can we offer?

We mainly offer steel grating, stair treads, trench covers, welded steel manhole covers, rainwater gratings, recessed manhole covers, and customized steel structure components.

Our products are widely used in petrochemical projects, nuclear power projects, municipal engineering, wastewater treatment plants, industrial platforms, residential areas, parks, ports, airports, and construction supporting facilities.

What logistics do we ship through?

For project orders, we provide integrated delivery support, including product coordination, packaging recommendations, loading arrangements, and shipment planning.

We can adjust the packaging method and delivery schedule according to different project requirements, and support batch delivery when needed. This helps customers reduce communication costs and keep project delivery more manageable.

Can it be customized as per our requirements?

We offer drawing customization, non-standard custom manufacturing and full supporting production for engineering projects.

Our technical team provides one-on-one technical communication. We adopt professional software for drawing deepening and arrange production strictly per your project demands. Customization is available on materials, surface finishes, load standards, dimensions and installation accessories.

What is our ordering process?

Our general ordering process is:

Requirement confirmation → Drawing/specification review → Technical communication → Quotation → Sample or drawing confirmation → Production → Quality inspection → Packaging → Delivery

For non-standard products, early communication and sample preparation usually take around one month. For regular production capacity, our steel grating output can reach about 100 tons per day, and our welded manhole cover output can reach about 1,000 sets per day.
