Industrial Boiler Manufacturing in Malaysia and Indonesia
Boiler Manufacturing Built Around Quality and Reliability
Mechmar has developed its manufacturing capabilities over five decades of industrial boiler engineering and fabrication.
Our facilities in Malaysia and Indonesia support the production of industrial boilers and thermal-energy equipment for customers across Southeast Asia and other international markets. Maintaining our own manufacturing capabilities gives us greater control over material quality, fabrication standards, inspection procedures and production schedules.
Our manufacturing scope includes:
- Fire-tube steam and hot-water boilers
- Water-tube boilers
- Biomass and solid-fuel boilers
- Oil- and gas-fired boiler systems
- Thermal-oil heaters

- Waste-heat recovery boilers
- Economisers
- Pressure components and boiler auxiliaries
- Customised boiler and steam-plant equipment
Two Regional Manufacturing Facilities
Mechmar operates two manufacturing facilities that support our customers across the region.
Manufacturing Facility in Johor, Malaysia
Mechmar’s Malaysian manufacturing facility in Johor has supported the company’s boiler-production activities since the manufacture of its first boiler in 1977.
The facility combines experienced fabrication personnel, production equipment, inspection processes and engineering support to manufacture boilers for a wide range of industrial applications.
PT Mechmar Jaya Industries, Medan, Indonesia
Mechmar strengthened its regional manufacturing capability with the establishment of PT Mechmar Jaya Industries in Medan, Indonesia.
The facility enables Mechmar to support customers in Indonesia and neighbouring markets while maintaining the group’s established manufacturing and quality requirements.
Controlled In-House Fabrication
Critical fabrication activities are managed internally wherever appropriate, giving Mechmar closer control over workmanship, production quality and compliance with approved engineering drawings.
Depending on the equipment and applicable requirements, manufacturing activities may include:
- Material preparation and cutting
- Plate rolling and forming
- Welding and assembly
- Tube installation and expansion
- Pressure-part fabrication
- Dimensional inspection
- Non-destructive examination
- Hydrostatic testing
- Surface preparation and painting
- Final inspection and documentation
All manufacturing should be performed according to the approved design, applicable fabrication procedures and relevant project requirements.
Material Quality and Traceability
Reliable boiler performance begins with the selection and control of suitable materials.
Mechmar sources specified materials from recognised suppliers and steel manufacturers. Materials are checked against the applicable technical specifications before entering the fabrication process.
Material-control procedures may include:
- Verification of material certificates
- Confirmation of material grade and dimensions
- Visual inspection
- Material identification and traceability
- Review against approved engineering specifications
- Independent inspection when required by the applicable code, authority or customer
These controls help ensure that the materials used in production meet the requirements of each boiler or pressure-equipment project.
Quality Assurance Throughout Production
Quality control is integrated throughout the manufacturing process rather than being limited to the final inspection.
Inspection activities are carried out at defined production stages to identify and address potential issues before the equipment progresses to the next stage. Depending on the project, inspections may be conducted by Mechmar’s quality personnel, customers, regulatory authorities or qualified independent inspectors.
This systematic approach supports:
- Consistent fabrication quality
- Compliance with approved procedures
- Accurate production records
- Material traceability
- Reliable equipment performance
- Safe long-term operation
Modern Equipment and Continuous Improvement
Mechmar continues to invest in manufacturing equipment, production methods and automation technologies to improve fabrication accuracy, consistency and operational efficiency.
These investments help our teams maintain dependable production standards while responding to changing customer expectations, engineering requirements and industry practices.
