About us

DINGHAO INTERNATIONAL ADVANCED MATERIALS AND TECHNOLOGY (THAILAND) CO., LTD. is a Thailand-based manufacturer and total solutions provider for aluminum extrusions.

Officially established on April 25, 2024, with a registered capital of THB 250 million, the company is strategically located in Pinthong Industrial Estate (Phase 6), Rayong Province, Thailand. Our manufacturing campus comprises two plants: Phase I covers approximately 28,944 m² (18.09 rai), and Phase II spans 69,840 m² (43.65 rai). The integrated facility houses extrusion workshops, anodizing lines, deep‑processing shops, and supporting quality‑control laboratories.

We specialize in the production of industrial and architectural aluminum profiles, with a core focus on photovoltaic (PV) frames and mounting brackets, as well as a broad range of custom structural profiles. With an annual capacity of 50,000 metric tons, we offer a complete, end‑to‑end production chain — from customized mold design and precision extrusion, to Thailand’s most advanced and largest automatic anodizing line, and fully automated finishing processes. Backed by a seasoned technical team, our vertically integrated operations enable us to efficiently fulfill diverse and complex customer requirements with consistent quality and on‑time delivery.

Our Core Products

We focus on four core product families that serve the solar energy and industrial equipment markets across Southeast Asia and beyond.

1. Solar Aluminium Profiles

Used in PV mounting structures, ground mount systems, rooftop installations, solar carports, and tracking systems.

Key features: lightweight, high strength-to-weight ratio, excellent corrosion resistance, designed for 25+ years outdoor service life.

2. Solar Aluminium Frames

Precision frames for solar modules that ensure dimensional accuracy, consistent surface finish, and reliable glass-module assembly.

Key features: tight tolerances, stable anodizing/powder coating, impact resistance, and compatibility with automated module production lines.

3. Industrial Aluminium Profiles

Standard and custom extrusions for automation equipment, conveyor systems, machine guards, workstations, assembly lines, and structural frameworks.

Key features: modular design options, multiple groove systems, various surface treatments (mill finish, anodized, powder coated), and high straightness.

4. Industrial Aluminium Frames

Finished or semi-finished frames for industrial enclosures, control cabinets, machine bases, protective barriers, and custom equipment housing.

Key features: pre-cut, pre-drilled, and assembly-ready options; robust corner connections; scalable for small to large industrial applications.

Our Competitive Advantage

🔹 Thailand-based manufacturing, ASEAN-focused service

We produce locally in Thailand, giving you shorter lead times, lower logistics costs, faster technical support, and reduced supply chain risk compared to importing from China or distant markets.

🔹 Strong dual-parent company backing

From Dinghao: extrusion technology, mould engineering, process optimization, and quality control systems.

From C&D: stable raw material supply, working capital, global trade network, and long-term business credibility (Fortune 500).

🔹 Quality consistency for mission-critical applications

Whether it is a solar farm requiring 10,000 identical frames or an automated production line needing precision profiles, we maintain strict extrusion tolerances, stable surface finish quality, and export-ready packaging.

🔹 One-stop solution for both solar & industrial

Many suppliers focus on only one segment. We serve both – and we understand the specific requirements of solar projects (weather resistance, high volume, cost efficiency) and industrial applications (precision, modularity, durability).

🔹 Supply stability you can rely on

With joint venture governance, diversified raw material sourcing, and strong financial backing, we minimize production and delivery risks – even during market volatility.

Our Mission

To deliver reliable, high-quality aluminium extrusion and framing solutions that help solar and industrial customers build faster, stronger, and more cost-effectively – manufactured in Thailand, backed by world-class Chinese partners.
