Design
In steel structure construction, design not only determines the cost but also the construction schedule and safety. We provide end-to-end design services, ranging from scheme optimisation to the development of detailed construction drawings. We fully understand the importance of ‘controlled changes’ and ‘drawing compliance’ in the procurement process, and ensure that every drawing strikes the right balance between cost-effectiveness and constructability.
We can provide you with a clear tax-inclusive quote in RMB. Commercially, we are highly flexible and can fully accommodate your agency export model. However, technical communication requires specialized personnel, as it pertains to structural safety and whether the final application meets requirements. This is central to project success and reflects our professional responsibility.We look forward to advancing the project together with you and your team.
The structural service life is determined by your project’s objectives and local codes. Based on these requirements, we design to ensure the structure meets its intended purpose. Whether your goal is 50, 70, or 100 years, we have corresponding technical solutions to match your expectations.
We can provide an itemised quotation.
For large-span structures, roof waterproofing is central to ensuring long-term building usability and structural safety. It is not merely a matter of “materials,” but rather a systematic engineering design. At LF, we provide reliable comprehensive waterproofing solutions through two key approaches: “system selection” and “construction design.” We recommend the most suitable waterproofing system based on your building’s form, budget, and local climate characteristics. Through rigorous design implementation, we fundamentally eliminate potential leakage risks.
This is a crucial question you’ve raised—one that nearly all professional clients weigh before making their final decision. We firmly believe that what LF offers isn’t a“higher price,”but rather“more comprehensive, more responsible value.”We encourage you to make a fair comparison and stand ready to engage in an in-depth discussion to help you make the most informed decision.
If the customer requires thermal insulation properties, LF can provide materials and structures that meet their requirements.
The primary function of the main steel structure is load-bearing; the material itself does not possess significant thermal insulation properties. A building’s thermal insulation performance is primarily achieved through the “envelope system,” namely the roof and walls. As an integrated solutions provider, we coordinate the design and integration of this system with the main structure.
If clients require thermal insulation, LF will recommend the most cost-effective insulation system solution based on your project location’s climate data, building purpose, and local energy efficiency codes.
As raw material prices fluctuate, we will recommend suitable roofing materials for each specific project and provide clients with quotations based on the current market prices for the materials in question.
At LF, we provide clients with end-to-end solutions for large-span buildings. Please provide us with the basic details of your project, and we will immediately carry out a professional preliminary selection of roofing systems for you, accompanied by a quotation based on recent projects that will serve as a useful reference.
Projects designed to American standards typically incur costs 20-30% higher than those designed to Chinese national standards. This represents an overall estimate.
LF recommends clarifying standard requirements early in the project to enable us to provide the most accurate quotation reference.
Yes. Before designing LF buildings, clients must provide necessary parameters, including storm and earthquake data. If such parameters are supplied during the design phase, the structure can withstand these events.
Whether to incorporate storm and earthquake resistance significantly impacts project costs, so no blanket statement can be made.
Based on your project budget and risk tolerance, LF will assist you in making the most informed decision. We never recommend unnecessary over-engineering, nor do we compromise safety standards for cost reduction.LF possesses extensive experience successfully delivering projects in multiple high-wind-pressure zones and high-intensity seismic regions globally, and we are ready to share technical insights from relevant case studies.
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.
Company Type
Choosing a steel structure supplier is, in essence, choosing a long-term partner. We are well aware that ‘delivery reliability’ and ‘after-sales responsiveness’ are key concerns for our clients, and we are committed to ensuring that every purchase you make is both reassuring and hassle-free through transparent collaboration processes and a comprehensive service network.
Yes. Depending on the project requirements, we can dispatch professional engineers to supervise the installation or provide a full on-site installation team.
Steel structures are easy to install and the process is very quick. We provide assembly videos to ensure that customers can learn how to install them within 10 minutes. Of course, to ensure safe, accurate and efficient installation, our engineers must oversee the work.
We always respect and support our clients in choosing the most suitable installation method based on their specific circumstances. For simple, standard flat grid projects, it is entirely feasible for the client team to install the structure themselves following our provided installation manual. We can offer video technical support to address any installation challenges that may arise during the process.
For any project involving large spans, complex geometries, or strict schedule requirements, we strongly recommend installation by our professional team or under the guidance of our engineers. This approach maximizes safety, ensures timely completion, and guarantees the highest final quality.
Our goal at LF is to ensure your project is completed safely and successfully, regardless of the installation method chosen.
As we are unfamiliar with labour costs and other relevant expenses in the client’s country, we can provide an estimated installation cost based on the conditions under which skilled Chinese workers would carry out the installation, for the client’s reference. In our experience, it takes foreign workers at least twice as long to complete the installation as it does Chinese workers.LF engineers will provide installation instructions and will be on site to supervise the installation.
Our engineers will draw up an installation schedule based on the specific circumstances of each project and submit it to the client.
Yes. We offer professional overseas project installation services. If needed, we can dispatch experienced Chinese technical workers and engineers to the project site for guidance and installation. However, the client is responsible for covering the workers’ visa fees, airfare, accommodation, and meals, as well as paying the Chinese workers’ wages. We look forward to applying our globally accumulated installation expertise to your project to ensure its complete success.
Yes. Providing professional installation guidance is not only a service option at LF, but also a key part of ensuring project success and realizing the design value.
We offer two main installation modes to suit different project budgets and complexities. We are committed to being your most reliable partner, tailoring a detailed installation plan and quotation to your specific needs.
