Electrical panels and factory wiring across Saraburi, the Eastern Seaboard and Greater Bangkok

Our panel workshop is in Chaloem Phra Kiat, Saraburi, and our installation teams work regularly across seven of Thailand's main industrial provinces.

Seven provinces we serve regularly

Every panel is designed, assembled and tested at our Saraburi workshop before it is shipped for installation, so quality is controlled at source and less work has to happen inside your plant.

Saraburi (our workshop)

Our office and panel workshop are in Chaloem Phra Kiat, serving plants around Kaeng Khoi, Nong Khae, Na Phra Lan, Wihan Daeng and Nong Khae Industrial Estate. Most clients here are cement, ceramics, marble and granite, food and steel producers.

Ayutthaya

About 60 km from our workshop, covering Rojana, Ban Wa (Hi-Tech) and Bang Pa-in industrial estates and the Wang Noi industrial area. Typical work: machine control panels, MDB panels and electrical upgrades for electronics and automotive parts plants.

Pathum Thani

About 90 km away, covering Navanakorn and Bang Kadi industrial estates plus Rangsit, Khlong Luang and Lam Luk Ka. Common projects are motor control panels, VFD panels for pump and fan systems, and electrical work in warehouses and food plants.

Bangkok

About 110 km away, serving plants in Lat Krabang, Bang Chan and Rama 2 as well as commercial buildings. Work here is mostly replacing end-of-life main switchboards, refurbishing electrical rooms and adding circuits for new loads.

Samut Prakan

About 140 km away, covering Bangpoo and Bang Phli industrial estates, Theparak, Bangna-Trad and Phra Pradaeng. Clients here are typically metal finishing, plastics, packaging and automotive parts factories.

Chonburi

About 170 km away, covering Amata City Chonburi, Laem Chabang, Pinthong and WHA estates inside the Eastern Economic Corridor (EEC). Typical work: production line control panels, PLC panels and power installation for new machinery.

Rayong

About 230 km away, covering Map Ta Phut, Eastern Seaboard, Amata City Rayong, WHA estates and the Pluak Daeng area. Plants here usually have strict safety and site-entry requirements, so our team prepares the required documents and protective equipment before every visit.

Other provinces

Outside these seven provinces we review projects individually, particularly panel work that is built at our workshop and shipped for installation. Send the site location together with your quotation request.

How we keep out-of-province downtime short

Our process for clients outside Saraburi is built around one goal: keeping the power-off window as short as the job allows.

  1. 1

    One thorough site survey

    Engineer and installation team visit together to capture loads, installation space, the existing system and the route for moving panels in — all in a single visit.

  2. 2

    Drawings approved before we build

    You review and approve the single line diagram and panel drawings before any equipment is ordered or assembly begins.

  3. 3

    Assembled and tested in Saraburi

    Assembly, wiring, labelling and functional testing all happen at our workshop, so most problems are solved before the panel leaves us.

  4. 4

    Delivered and installed in your window

    We install during the window you choose — a weekend or a planned shutdown — then test the system and hand it over.

Service area FAQ

Do you work outside these seven provinces?

We consider projects anywhere in Thailand. These seven provinces are simply where our teams travel most often. If your plant is elsewhere, send us the site location and scope and we will confirm whether we can take the job before quoting.

Is there a charge for a site survey?

Please ask our team before booking a visit, as it depends on distance, project size and how many visits are needed. We always confirm the terms with you before the first survey.

Where are the panels built, and how do they reach our site?

Every panel is assembled and tested at our workshop in Chaloem Phra Kiat, Saraburi, then transported to your site for installation. This keeps build quality under our control and shortens the time our team has to spend inside your plant.

Can you work during shutdowns, weekends or night shifts?

Main switchboard replacements and other work requiring a power outage are usually done during plant shutdowns or non-production hours. Tell us your preferred window when you request a quotation so we can plan manpower and materials in advance.

What documents do you need to enter an industrial estate?

Safety requirements differ by estate and by plant: gate passes, work permits, safety induction and worker documentation. Send us your plant's requirements together with the project details so our team arrives with the correct paperwork.
