HIGH-RISE PREFABRICATED STEEL FRAME FOR RESIDENTIAL BUILDINGS
For apartment blocks and mixed-use towers we fabricate H-section or box columns and H beams that bolt together on site. Steel floor decking is placed on several floors at once, something a cast-in-place concrete building cannot do, so the structure rises much faster. The frame connects well with concrete cores and slabs, saving both steel tonnage and concrete. The exterior wall system follows the architect's design.

FREQUENTLY ASKED QUESTIONS
IS A STEEL BUILDING SAFE IN EARTHQUAKES?
Steel is ductile and bends rather than cracks, which makes steel frames a common choice in seismic zones. We design to the seismic intensity of your site.
HOW IS FIRE PROTECTION HANDLED?
Structural members can be coated with intumescent fire-resistant paint or encased in fire boards to reach the fire rating your local code requires.
WHAT DO YOU NEED FOR A QUOTE?
Dimensions (length, width, height or number of floors), the site location for wind, snow and seismic loads, the intended use, and your preferred roof and wall materials. A sketch or a photo of a similar building is enough to start.
CAN A STEEL FRAME BE USED FOR APARTMENTS?
Yes. Steel frames are widely used for multi-storey and high-rise residential buildings. The frame is lighter than concrete, goes up faster and leaves fewer interior columns, so layouts are more flexible.
HOW IS IT PACKED AND SHIPPED?
Members are numbered, bundled and loaded in 40 ft containers or on flat racks with a packing list and erection drawings. We ship FOB Ningbo or Shanghai, or CIF to your port.
CAN YOU HELP WITH INSTALLATION?
Every order comes with erection drawings. For larger projects we can send engineers to guide your local crew on site.
