High-Strength Bolts for Steel Structures: A Complete Guide (Advanced Engineering Edition)
In modern steel structure engineering, high-strength bolts represent far more than a simple fastening component—they are the core transmission elements that guarantee joint rigidity, seismic resilience, and long-term structural integrity. In critical steel connections, the performance of the bolts often determines the safety margin of the entire structure. This in-depth guide explains not only what high-strength bolts are, but also why they matter, how t...Read more -
How Longshi Provides Reliable Fastener Solutions for Low-Temperature Projects
Low-temperature environments increase the risk of brittle fracture in fasteners used for pipelines, petrochemical plants, LNG facilities, and high-altitude structures. This article introduces Longshi’s professional fastener solutions designed to ensure bolt safety from –20°C to –60°C.1. The Challenge of Low-Temperature Bolt FailureWhen steel operates below its ductile–brittle transition temperature, it loses toughness rapidly. For pipelines, c...Read more -
