Why Most Space Frame Projects Fail
On long-span steel space frame projects, a single weak link — a late shipment, an unqualified weld, an unmanaged installation crew — can turn a profitable project into a liability. Here is where most EPC partners fail your project.
Missed Fabrication & Shipping Deadlines
Under-capacity factories and disorganized logistics push steel members past your steel erection window, stalling the entire site schedule.
Uncertified Steel & Weak Ball Joints
Mislabeled grades and unverified welds on nodes and bolted spheres put your 30m+ span at risk of long-term structural failure.
Poorly Managed Erection Sites
Untrained crews and weak on-site supervision during high-altitude lifting cause accidents, rework, and irreversible schedule losses.
Where HBK Space Frames Perform
A single structural system engineered to cover the widest, most demanding spaces — without interior columns.

Fully Customized to Your Project
No two sites are the same. Our engineering team tailors every parameter of the space frame system to your load requirements, climate, and architectural intent — free of charge.
Span & Grid Geometry
Custom clear spans from 20m to over 150m, with square, diagonal, or hybrid grid configurations.
Ball & Node Systems
Bolted-ball, welded-ball, or plate-connection joints selected per load and durability needs.
Roof Cladding Options
Metal sandwich panels, membrane structures, skylights, or curtain wall integration.
Coating & Climate Rating
Hot-dip galvanizing, fluorocarbon paint, and corrosion systems rated for coastal, desert, or high-humidity zones.
