Product Description -Steel Structure Construction

Key Performance Traits

1. Exceptional Strength & Load-Bearing Capacity
   Steel’s high tensile and compressive strength allows it to support heavy loads (e.g., machinery, large spans, or multiple floors) without deformation, making it ideal for structures requiring durability under stress.
2. Durability & Resistance
   When properly treated—such as with anti-corrosion coatings or galvanization—steel demonstrates strong resistance to rust, rot, pest infestations, and harsh weather conditions like wind, rain, and snow. It retains its structural integrity reliably for decades, with service lives that often surpass 50 years.
3. Design Flexibility
   Steel’s malleability enables diverse architectural designs, including large column-free spans (critical for warehouses, stadiums, or open-plan offices) and complex shapes. This flexibility adapts easily to evolving functional needs.
4. Efficient Construction
   Steel components are typically prefabricated off-site—undergoing cutting, welding, and shaping in controlled factory environments—greatly reducing on-site labor requirements and construction time. Even for components that require partial on-site fabrication, steel’s inherent ease of assembly (e.g., via bolted connections or quick welding) still shortens project timelines significantly when compared to traditional concrete construction.
5. Sustainability
   Steel is 100% recyclable, and many components use recycled materials. Its long lifespan and low maintenance needs also minimize environmental impact over the structure’s lifecycle.

Quality Control

• At TSIN, we regard quality as the cornerstone of our services—a defining attribute that guides every aspect of our work. We are fully committed to delivering exceptional quality products and services across all stages of a project’s lifecycle, from initial planning to final handover.
• To uphold this commitment, we implement rigorous quality control protocols: we conduct thorough inspections of all raw materials before fabrication begins, and perform a second round of checks after production to ensure compliance with standards. Our fabrication and welding teams, comprising highly trained professionals with specialized expertise, offer a comprehensive range of customized fabrication services tailored to meet your project’s unique requirements.
• Our core fabrication processes adhere to strict precision standards, including:
• Accurate measuring, cutting, and welding of steel components
• Precise placement of holes and cleats to align with design specifications
• Systematic packaging and sequential loading to prevent damage during transit
• Safe dispatching to the construction site, with optional on-site erection services available upon request

Paking and Inspection

FQA:

Q1: Can I have a visit to your factory before the order?
A: Why not? welcome to visit our factory. You can fly to Qingdao Airport.We will pick you up in the airport. Hotel booking service is available

Q2:How do we cooperate on certatin project?
A: 1. Please send us your project details and your requirements.
2. We will design accordingly, free of charge. Afterwards, please check and confirm whether you like the drawings. If not, we shall get the drawings revised until your confirmation.
3. Pay 30% deposit after signing contract
4. Confirm the details of the design
5. Production and pay the final payment before shipment
6. Supply Installation service on line or paid installation

Q3: What is the price range of steel structures and steel warehouses?
A: The price of steel structures and steel warehouses on Alibaba varies depending on factors such as material quality, size, and design complexity. Generally, the price per square meter can range from tens of dollars to hundreds of dollars. For example, some small - scale simple steel warehouses may start at $19 per square meter, while large - scale, high - quality steel structures may cost $100 or more per square meter.

Q4: Do you supply installation service?
A: We will furnish you the detailed construction drawing and the construction manual which could help you to erect and install the building step by step or even on - site installation services.
If needed, our workers and engineers could be sent to the construction site for installation help. The daily salary, accommodation cost, flight cost, food fee will be paid by the BUYER.

Q5:What is the delivery time?
A:Delivery time depends on order quantities and size of building. Generally, the delivery time will be 30 days after receiving
deposit.And partial shipment is allowed for big order.

Q6: What is the anti-rust treatment for steel structure?
A: Anti-rust treatment of steel structure
Normal anti-rust paint
Anti-rust paint with epoxy zinc primer
Hot-dip galvanization
Hot-dip galvanization+PU finish
Stainless steel structure: No.301/304/316 stainless steel structure.

Q7:How about your quality control?
A:Our products have passed CE EN1090 and ISO9001:2008. We will submit product quality inspection reports to ensure that the materials and manufacturing processes meet high - quality standards.

Q8: Why your price is higher than other suppliers?

Our price is higher because we use top steel from major mills in China, smarter designs that balance safety and economy, durable high grade panels/parts (lasting 10–20 years), and avoid cheap shortcuts. A steel structure isn’t disposable—cutting costs now means big repairs later. We prioritize long-term value, not low initial prices.
