Design-to-fabrication for high-rise steel buildings (100+ stories). Steel: ASTM A992/A572 Gr.65. Moment/braced frames, CFST. CNC ±2mm precision. Fire-rated + anti-corrosion. 50+ year life. AISC/IBC compliant.

High-Rise Frame Steel Structure Design, Fabrication & Processing

High-Rise Steel Frame Structures | Greater Design Flexibility and Space Utilization

 

Core Features & Advantages

High-rise steel frame structures—leveraging high-strength steel and lightweight design—reduce a building’s self-weight by 40% compared to concrete structures, thereby significantly lowering foundation loads and providing a more stable lateral-force-resisting system for super-high-rise buildings. By integrating structural components with cantilevered elements and skybridges, these structures facilitate dynamic spatial interaction. Regardless of the desired architectural form or functional requirements, this system adapts with ease.

♦ In-house design & fabrication;

♦ 50% faster construction;

♦ Magnitude 8+ seismic resistant;

♦ 40% lighter, 12–15m spans;

♦ ±2mm precision;

♦ Fire-rated, 50+ years;

♦ 100% recyclable.

Applications

High-rise steel frame structures, through custom design, are widely utilized in urban landmark complexes, super high-rise office towers, and high-end commercial centers. By incorporating large-span, column-free spaces and cantilevered structural designs, they effortlessly facilitate three-dimensional interactive environments—such as soaring atriums and skybridges—thereby meeting the flexible requirements of modern office spaces.

♦ Commercial offices;

♦ Residential towers;

♦ Mixed-use;

♦ Hotels;

♦ Government buildings;

♦ Landmark projects.
