PPGI Window Frames
PPGI window frames are widely used in construction because of their durability, resistance to corrosion, and the appearance.
Overview

PPGI window frames are long-lasting, easy to maintain and give a good look to the building construction. PPGI window frames are made using a corrosion-resistant galvanized iron core and a pre-painted coating to ensure that the frames are not easily affected by weather conditions hence lasting longer. They come in several different colors and finishes and can be used to add a little more design freedom to a project and can be adapted to fit into various architectural designs. PPGI window frames are also cheaper, easy to fix, and can be made stronger to incorporate security measures. Ideal for the residential, commercial, and industrial buildings, they offer good thermal resistance and are perfect for use by builders and architects who would wish to find a good window framing solution.

Why PPGI Window Frames stand out from the rest

1.PPGI door frames are galvanized with a layer of zinc and are also pre-coated with superior quality paint. This affords them a very good level of protection against corrosion and therefore can be used in areas where there is high humidity or the environment is generally unfriendly.

2. The use of galvanized iron base and the pre-painted surface improves on the overall strength of the door frame. The PPGI frames are highly resistant to wear and tear and as such, they have a longer life span than most other materials.

3. Pre-painted finish of PPGI frames provides better and attractive look to the frames. They come in a number of colors and finishes to suit any architectural design and can be easily matched.

4. The outer layer of PPGI door frames is a protective layer, thus they do not need much maintenance. The paint applied to the steel before fabrication cuts down on touch-ups and re-painting expenses in the future.

Step One:
Integrated Frame Design
Manvik’s single rebate window frames are crafted from PPGI/PPGL with an integrated vertical (jamb) and horizontal structure, eliminating the need for welding or grinding. The rebate channels on both jamb and head improve sealing, reducing drafts and enhancing security. Embossed, interlocking corners with strong riveted connections boost durability. A baked-on pre-painted finish prevents rust and chipping, offering a clean, long-lasting, and aesthetically pleasing window frame solution.

Step Two:
Durable Hinge System
Manvik uses rivet technology to fasten window hinges without damaging the PPGI/PPGL sheets, avoiding rust-prone cuts and ensuring long-lasting durability. Hinges are well-anchored and protected by plastic caps that block construction debris. These features simplify installation and improve hinge longevity. Additional hinge caps eliminate the need for resizing during fitting, making the frame easier to install while maintaining a high standard of finish and functional performance.

Step Three:
Waterproof Frame Construction
Manvik’s single rebate window frames integrate vertical and horizontal sections without welding, preventing weak points for water entry. The rebate on the jamb and head creates a tight seal against drafts and moisture. Embossed, interlocking corners and a rust-resistant, baked-on finish enhance durability, offering a sleek, waterproof solution ideal for long-lasting protection in any weather condition

Custom Solutions
Every project is unique, which is why we offer custom-designed and sized PPGI window frames to meet specific architectural and functional requirements. Whether for residential, commercial, or industrial use, our frames ensure a precision fit, easy installation, and seamless integration. Ask ChatGPT
Commitment to Quality
Each frame undergoes strict quality checks from manufacturing to finishing. We ensure strength, durability, and visual consistency in every product. Our focus on quality delivers trusted, long-lasting performance that meets the highest expectations in construction and design.
Customer Service
We support clients from consultation to installation. Our team offers expert advice, timely updates, and personalized assistance to ensure smooth experiences. At Manvik, we’re committed to satisfaction, making sure every project is efficient, successful, and well-supported.
Advanced Finishing
Frames are finished with baked-on coatings and anti-corrosive treatments for long-lasting performance. These finishes resist chipping, weather effects, and wear while maintaining a refined appearance—ensuring both functional durability and visual appeal in environments, indoor or outdoor.
Key Benifits
PPGI window frames can be easily installed as they are light in weight and are fabricated in advance before the actual construction. Most of the frames are designed with pre-punched holes and corner interlocking to facilitate on-site construction without necessarily welding. Hinges and locking systems can be easily fixed to the door frame through rivet technology to enhance the ease of installation.
Indeed, the use of PPGI window frames can be regarded as more environmentally friendly. While galvanization and pre-painting uses environment friendly coatings most of the time. Further, its long life cycle as well as the low need for maintenance results in minimum replacement, which is environmentally friendly in the construction industry.
The PPGI window frames do not corrode easily hence can be used in different areas of the world such as the areas with high humidity and areas near the sea. They are suitable for both hot and cold conditions, and are not affected by changes in temperature and weather conditions.
