SDKM builds bespoke steel frame buildings for retail and supermarket projects.
Our engineers tailor every span, height, and layout to your store plan.
We handle design, fabrication, and installation guidance in one team.
Therefore, you get one partner from first sketch to final handover.

Shopping layouts change fast, so fixed structures often waste valuable space.
Our bespoke steel frame building grows with your retail business.
Moreover, we adjust column positions to protect your aisle flow.
We reinforce roof sections for signage, HVAC units, and solar panels.
As a result, your store runs efficiently from day one.
We produce a flexible dimension steel structure in any length and width.
Standard bays, mezzanines, and loading docks all fit our frames.
In addition, we offer clear spans from 20 meters to 80 meters.
You can expand your supermarket later without a rebuild.
Besides, our bolted connections make that expansion simple.

Our custom retail commercial building meets local wind, snow and seismic codes.
We galvanize or paint every steel member for long service life.
Furthermore, insulated sandwich panels keep shopping floors comfortable and energy efficient.
We ship prefabricated components in containers and guide your installers on site.
Finally, our team supports you until your store opens.
We use Q235 and Q355 structural steel.
We weld heavy-duty H-section portal frames.
Also, we offer 20 m to 80 m clear spans.
We install sandwich panels or color steel sheets.
Plus, we fit sliding, rolling or glass storefront doors.
We finish steel with hot-dip galvanizing or powder coating.
