I. Basic Design Principles Lightweight roof purlins (especially cold-formed thin-walled steel purlins) are sensitive to snow loads; they must be verified against the most unfavorable scenario of non-uniform snow distribution, rather than being assessed solely based on uniform distribution. II. Class...
Choosing the wrong purlin can lead to issues such as the inability to install roof panels, failure to support the required loads, or premature failure due to corrosion within just two years. Below, we clarify the differences, suitable applications, and key selection criteria for four common types of...
The steel truss-arch is a spatial structural form that combines the load-bearing mechanism of a truss with the geometric advantages of an arch, thereby integrating the truss's efficient load transfer characteristics with the arch's superior performance under compression. Based on cross-sectional con...
Root Causes of the Price War Mr. Zhang opened by pointing out that the root cause of price wars lies not in costs or distribution channels, but in a lack of "perceived value" and "trust." When products are commoditized, customers have no choice but to compare prices; furthermore, companies with an O...
Definition and Key Feature Rigid tie rods are longitudinal structural members that can resist both tension and compression, distinguishing them from flexible tie rods (e.g., round bars, cables, or wire ropes) which are tension-only. This dual capability makes them critical for force transmission in ...
At Yumisteel, continuous learning is part of our culture. Alina, our training coordinator, organizes an internal knowledge-sharing session every month to keep our sales and engineering teams sharp. This month Jack lead the session on Steel Structure Product Knowledge. Colleagues eager to deepen thei...
This article compiles essential knowledge on profiled steel sheeting, from nomenclature rules defining section types to key performance advantages such as high strength to weight ratio and structural efficiency. Particular attention is given to the rib/crown geometry, which dictates load bearing cap...
Polyurethane sandwich panels are among the most versatile building materials in modern construction. Composed of a rigid polyurethane foam core bonded between two metal facings,typically steel or aluminum,these panels deliver exceptional thermal insulation and structural strength. Their applications...
Yumisteel will observe the Dragon Boat Festival holiday from June 19 (Friday) to June 21 (Sunday), 2026. Normal operations will resume on Monday, June 22, 2026. Important Operational Arrangements: Office Support: Although our office will be closed for the statutory holiday, a dedicated team will rem...
Designing profiled steel sheeting composite slabs requires careful consideration of load capacity, fire resistance, and shear connection. This guide covers step-by-step methods for safe, efficient composite floor design. From deck selection to reinforcement detailing, you will learn industry best pr...
Choosing between closed, open, or re-entrant deck affects fire safety, installation speed, and total cost. One comparison table makes the right call easy. How to quickly identify the three deck profiles? Type Section Feature Typical Model Composite Deck Rebar Requirement Open (Deck) Open rib facing ...
Floor decking, also known as profiled steel sheet or steel decking, is a type of metal sheet made by cold-rolling or hot-rolling galvanized steel sheets into a specific corrugated cross-section (commonly V-shaped, U-shaped, and trapezoidal), as shown in the image below. Floor decking primarily serve...
