We build each door frame with our own aluminum profiles, patented in Brazil. The profiles have thick walls that give the frame a sturdy construction. Our engineering team uses SOLIDWORKS to design the frame around the dimensions and design of each door. We join the profiles using precision laser welding.
We fill every door with rock wool to help reduce heat transfer and sound transmission through the door.
ACM stands for aluminum composite material. Our 4 mm exterior panels consist of two thin aluminum sheets bonded to a low-density polyethylene (LDPE) core. This construction produces a lightweight panel, and a PVDF coating helps protect the exterior finish from exposure to the elements.
Choose from more than 100 finishes, including solid colors, metallics, and textures that evoke wood, concrete, granite, and marble. The ACM panels carry a 15-year warranty, subject to the applicable warranty terms.

Titan ACM Doors manufactures custom aluminum composite material (ACM) entry doors for high-end residential projects. We combine aluminum construction, a wide selection of finishes, and custom dimensions and designs to serve architects, builders, dealers, and homeowners.
We are the international brand of Gralha Azul Portas, a Brazilian door company founded in 1991 and now led by the second generation of the family. In 2020, we opened our dedicated ACM door manufacturing facility to meet the demand for entry doors that combine weather resistance, security, and design flexibility.
Our 16,000-square-foot manufacturing facility brings together a specialized team and technology dedicated to ACM door production. We have developed proprietary structural profiles, patented in Brazil, that enhance our door construction and manufacturing process.
Our doors feature an aluminum structure, mineral wool insulation to support thermal and acoustic performance, and ACM panel surfaces. With more than 100 color and finish options, including solid colors, wood-look finishes, and metallics, each door can be tailored to complement the home’s architecture.
Our portfolio spans traditional and contemporary designs, from conventionally sized entrances to oversized entry doors. Patterns, textures, glass elements, handles, weather seals, and locking systems are selected according to the door configuration and the requirements of each project.
We work with architects, builders, and dealers to refine these selections, reviewing project drawings and providing technical guidance throughout the ordering process. Material selection, manufacturing precision, and attention to finish details guide every stage of our work.
We began exporting in 2023. Today, our doors are featured in projects in New York, Miami, Dubai, and Kuwait, bringing Brazilian manufacturing expertise to a range of markets and architectural styles.
