Production
The factory is the cornerstone of product quality. Our production system strictly adheres to end-to-end quality control standards. Through digital production scheduling and capacity reservation mechanisms, we ensure the machining precision and timely delivery of large-span and irregularly shaped components, ensuring that your project schedule is not held up by factors on the factory side.
Our minimum order value is USD 15,000. The delivery time will depend on the structural corrosion protection requirements and the roofing materials.
The minimum order quantity is at least 10 tonnes, and the delivery time is approximately one month.
The price difference between standard and premium anti-corrosion treatments can be 5–8 times, or even more.
Yes.LF warmly welcomes and fully supports clients sending engineers to our factory for on-site quality supervision and communication.
This not only enhances your confidence in the project progress but also exemplifies LF's commitment to transparent collaboration and joint quality assurance.
If the materials specified in the drawings can be procured compliantly on the market, we will prioritize their use. However, due to limited manufacturers, prices may be relatively higher. When original standard materials are unavailable, our company adheres to the principle of equivalent strength substitution for production and processing. Whether using original standard materials or equivalent strength alternatives, LF will meet your requirements and provide professional solutions.
This should be determined in accordance with ISO 12944, taking into account the specific circumstances of each component.
LF operates three manufacturing facilities where all core structural components are produced in-house. This enables us to implement rigorous end-to-end management—from raw materials and production processes to final quality control—ensuring consistent and reliable product quality. It is precisely this absolute control over the manufacturing process that empowers us to deliver safe, compliant, and on-time steel structure products to customers worldwide.
This is a highly specialized question. The thickness of a steel structure is not a fixed value but is determined through a series of rigorous calculations. It primarily depends on several key factors: span size, load conditions, column grid dimensions, support conditions, grid configuration, construction requirements, architectural functions, and client specifications.
As a preliminary empirical reference under conventional loads:
Planar structure thickness may range from 1/10 to 1/18 of the shorter span.
Shell thickness may range from 1/30 to 1/60 of the span.
Therefore, after understanding your project and requirements, LF will provide a customized solution.
The maintenance cycle for an anti-corrosion system is not a fixed value but is determined by the coating system design, construction quality, and the specific corrosion environment of the project. Standard anti-corrosion protection typically lasts 5-8 years, while advanced systems can exceed 15 years. During project design, LF will clearly define your project's target service life and provide a corresponding coating specification that meets international standards, making the maintenance cycle predictable and plannable.
