SMART CONSTRUCTION · DESIGN · ROLL-FORM · BUILD
Villas framed in steel. Built in half the time.
APEX designs, roll-forms and erects light-gauge steel structures for villas, resorts and clubhouses, from our own factory in Lamai, Koh Samui.

STEEL FRAME
CLADDED
CERTIFICATIONS & STANDARDS
STEEL GRADE
G550 high-tensile steel
Our frames are roll-formed from G550 structural steel, with a minimum yield strength of 550 MPa as defined in AS 1397. Higher strength allows thinner, lighter sections carrying the same loads.
COATING
ZM275 zinc-aluminium-magnesium coating
A hot-dip zinc-aluminium-magnesium coating of 275 g/m² (both sides combined). Magnesium gives better corrosion resistance than plain zinc and protects cut edges, which suits humid, salty island air. Coil sourced locally from BlueScope Thailand carries SuperDyma® 180 Zn-Al-Mg coating, which performs comparably to ZM275.
MATERIAL STD
AS 1397:2021 coated steel sheet
The Australian standard for continuous hot-dip metallic coated steel sheet and strip. It defines the steel grade (G550) and coating class (ZM275) that we specify for every coil.
THAI STD
Thai Industrial Standards (TISI)
Steel must comply with Thai Industrial Standards to be sold in Thailand. Imported coil must meet both Thai and international standards. Locally produced coil comes from TIS-certified Thai mills such as BlueScope.
DESIGN STD
AS/NZS 4600:2018 cold-formed steel structures
The primary design standard for light-gauge, cold-formed steel. Our LGS specialist engineers size every stud, truss and connection to it.
ENGINEERING
Certified by a licensed Thai structural engineer
Each LGS design is checked and signed by a Thai civil/structural engineer licensed by the Council of Engineers Thailand (สภาวิศวกร), as Thai building permits require.
PERMITS
Building permits approved on Koh Samui
Koh Samui’s planning department has approved building permits for APEX LGS projects under the Building Control Act B.E. 2522. Our drawings and calculations are prepared for permit submission.

THE METHOD
From coil to frame.
We don't deliver a pile of studs. We deliver a system, engineered and numbered before it reaches your site.
01We design it
A digital twin of your project. Every stud is engineered before it exists.
02We roll-form it
Our machines turn steel coil into custom studs in minutes, to 1 mm tolerance.
03We kit it
Every piece numbered, labelled and pre-punched, bundled in build sequence.
04We build it
Walls and trusses stand in days. No measuring, no cutting on site.
WHO WE BUILD FOR
Pick your role.
Your villa, framed in weeks, with no termite or rot worries.
Bring us drawings or an idea. We engineer the frame, fix the price early and keep you updated from factory to handover.
Speed
Frame stands in days, not months, so your builder can start finishing sooner.
Durability
Galvanised steel: no rot, no termites, no warping in the humidity.
Certainty
Steel price agreed upfront, one team accountable for the frame from design to erection.
APEX 3D LAB
Inspect every stud. Every connection.
Six real APEX frame models, slowly turning. Tap any one to rotate and zoom. These are the villa types we engineered for the Metrocon development.

WHY LIGHT GAUGE STEEL
Stronger. Faster. Straighter. Than masonry.
