Extensive Applications of Steel Trusses

Steel trusses feature high load capacity and cost efficiency for permanent and temporary constructions. Indoor applications include venue light hangers, LED screen supports and fixed theater lighting bridges. Commercially, they serve exhibition booths and showroom display frames. For events, they build backdrops for music festivals, wedding ceremonies and campus galas. Matched with electric lifting cylinder systems, they support heavy dynamic rigging for stadiums and large tents. Made of all-steel with good wind resistance, they adopt modular male-female connectors for quick assembly. Suitable for long-term indoor installation and short-term outdoor performances, they stand as the top choice for low-cost heavy-duty structural projects.

FAQs about Steel Trusses

Q
How long the deliver time?
-
+

General it is about 5-15 days.

Q
What’s the core difference between steel truss and aluminum truss?
-
+

Steel truss is made of Q355B steel with higher load capacity and lower cost, ideal for permanent venues and mass low-budget builds. Aluminum truss is lightweight, perfect for touring and frequently disassembled short-term events.

Q
What is the electric lifting cylinder system used for?
-
+

It realizes self-climbing erection of truss masts without large cranes. With electric synchronous lifting, it completes high-altitude installation of heavy trusses for lights, LED screens and roofs.

Q
Do steel trusses undergo load testing before delivery?
-
+

All steel trusses pass double inspections for load resistance and welding firmness before delivery, manufactured per domestic stage steel structure standards.

Q
What are the core advantages of your steel trusses compared with ordinary light trusses?
-
+
Our steel trusses are made of thickened Q355B steel, featuring significantly higher load capacity than ordinary light trusses. Meanwhile, they adopt cost-effective raw material solutions, with lower comprehensive costs, making them more suitable for heavy-duty use scenarios and large-batch procurement projects.
Q
What welding and anti-rust treatments are applied to your steel trusses to ensure durability?
-
+
The trusses adopt full penetration welding with integrated full welding of four-side braces, forming a solid overall structure with excellent anti-deformation performance. For anti-rust protection, dual treatments of hot-dip galvanizing and electrostatic spraying are applied, enabling long service life for both indoor and outdoor use.


Q
What size options and structural design features do your steel trusses have?
-
+
We provide complete 5/15/30 truss series with diverse sizes and matching fittings. Adopting standard modular design and unified dimensions with male-female connectors, the trusses support flexible assembly and can quickly form various frame structures to meet different layout needs.
Q
What application scenarios are your steel trusses suitable for?
-
+
They support both permanent and temporary constructions. Indoor scenarios include venue light hangers, LED screen supports and fixed theater lighting bridges. Commercial scenarios cover exhibition booths and showroom display frames. Event scenarios include music festival backdrops, wedding ceremonies and campus galas. They can also match electric lifting cylinder systems for heavy dynamic rigging in stadiums and large tents.
Q
Do you provide customized services for steel trusses?
-
+
Yes, we offer professional customized services. We can customize truss lengths and special shapes according to customers’ unique on-site construction requirements to adapt to personalized and complex project demands.
Q
What quality inspection standards do your steel trusses comply with before delivery?
-
+
We have self-owned processing and testing workshops and a complete mature technical system. All steel trusses will pass dual inspections of load performance and welding quality before delivery to ensure stable and reliable product quality.
Q
Why are your steel trusses highly cost-effective for engineering projects?
-
+
On the premise of high load capacity and stable performance, our steel trusses adopt low-cost high-quality raw materials, reducing overall procurement costs. They are especially ideal for mass orders and long-term fixed installations, with low later maintenance costs, realizing high cost performance for the whole project cycle.
Q
What are the environmental adaptability and assembly advantages of your steel trusses?
-
+
The all-steel structure provides good wind resistance, adapting to complex outdoor environments. Equipped with modular male-female connectors, the trusses support rapid assembly and forming. They are perfectly applicable to both long-term indoor fixed installation and short-term outdoor temporary performance projects, serving as the top choice for low-cost heavy-duty structural projects.
