 In the general notes of steel structure construction drawings, have you ever written a line like this: “Drafted, stamped, and issued.” Everything seems to flow smoothly. “For this project, Grade 1 welds shall undergo 100% non-destructive testing, Grade 2 welds shall be subject to 20% sampling inspection, and Grade 3 welds shall undergo visual inspection.” However, if someone were to ask at this moment, “Why must this weld be Grade 1, while that one can be Grade 2? Who exactly determines this ‘grade’?” would your answer still flow so smoothly? This question, though seemingly basic, represents the most fundamental—and yet most easily overlooked—underlying logic in steel structure welding design. The classification of weld quality grades is by no means arbitrary, nor is it a matter of the designer’s “whim.” It is underpinned by a clear, rigorous set of principles, proven through engineering practice, which directly determine the structural safety and service life of the structure.

Steel structure workshops, with their fast construction speed, low cost, and good sturdiness, are widely used in manufacturing and warehousing areas. However, in the hot summer, these workshops become sweat-evaporating chambers. Even without a hot production area, the temperature inside a steel structure workshop can be 5 degrees Celsius higher than the outside temperature, and the heat source temperature in the production area often reaches over 40 degrees Celsius. Environmental problems associated with steel structure workshops and sheet metal buildings include: 1. Large area and space make it difficult to find suitable ventilation and cooling equipment. 2. Poor insulation of sheet metal roofs leads to stuffy and hot workshops in summer. The heat generated by machinery in some steel structure workshops and sheet metal buildings accumulates if it cannot be expelled in time, increasing the workshop temperature, making it stuffy, and affecting the workshop environment. To solve the env...

 The roof of a space structure plays an extremely important role in a building—providing shelter from wind and rain and ensuring efficient drainage. Whether in large-span sports halls, exhibition centres, industrial plants or logistics warehouses, a well-designed roof drainage slope is key to ensuring the structure functions properly. If the slope is not properly managed, the consequences can range from minor issues such as water pooling and leaks—which affect the building’s aesthetics and service life—to more serious problems, such as structural safety risks caused by excessive water accumulation and dead loads during heavy snowfall or torrential rain. Therefore, the appropriate management of roof slopes is an aspect of space frame design that cannot be overlooked. So, what are the methods for handling roof slopes in space frame structures? There are generally three methods for handling roof slopes in space frame structures: 1. Installing small columns at the top chord nodes to cr...

Double-laminated glass, also known as laminated glass, is a composite glass product made of two or more sheets of glass with one or more layers of organic polymer interlayer sandwiched between them. After a special high-temperature pre-pressing and high-temperature, high-pressure process, the glass and interlayer are bonded together. Common interlayers include PVB (polyvinyl butyral), SGP (ionic interlayer), EVA (ethylene-vinyl acetate copolymer), and PU (polyurethane). These interlayers are transparent, elastic, have strong adhesion, and good penetration resistance. Even if the glass breaks, the fragments will adhere to the film, and the broken glass surface remains clean and smooth, effectively preventing injuries from shards and falling debris. Production Methods: 1) Film Hot-Pressure Method (Dry Method): The glass and interlayer are stacked in sequence and placed in an autoclave. They are then hot-pressed under specific temperature and pressure conditions to firmly bond the interla...

 Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of components such as beams, columns, and trusses made of steel sections and plates, and uses rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are usually connected by welds, bolts, or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, and high-rise buildings. According to different classification standards, steel structures are classified as follows: 1.Steel structures are classified into four types according to their uses: tall steel structures, plate and shell steel structures, industrial plant steel structures, and light steel structures. 2.Tall steel structures: Tall structures include television towers, microwave towers, communication towers, high-voltage transmission line towers, petroch...

 We encounter glass in our daily lives, and interior designers often leverage its advantages in home decor—such as enhancing the visual openness of a space and improving natural light. However, many homeowners worry that glass is fragile and could injure their children, so they hesitate to use it extensively. Today, we’ll explain the difference between laminated glass and ordinary, breakable glass. As the name suggests, laminated glass is a composite glass created through a high-temperature process that sandwiches EVA, SGP, or PVB adhesive between multiple layers of glass. Unlike ordinary glass, which is fragile, laminated glass holds together when broken, preventing sharp shards from causing injury or damage. It is commonly used in large-scale applications such as railings, glass canopies, windows, and flooring. Secondly, although laminated glass is thicker than ordinary glass, it does not affect natural light or transparency at all. Precisely because it is thicker, it reduces noi...
