A scholarship represents not only encouragement, but also recognition of a child’s hard work and persistence. 
Sanjiu Building Materials has long-term support for the Hawk Inline Skateboard team and is very happy to share the glorious moment with the children in this annual scholarship award event. 
From the sweat on the training ground to the smile at the award ceremony, every step accumulates growth and allows people to see that dreams are sprouting. 
We always believe that giving back to the society is not just a slogan, but through actual participation time and time again, accompanying more children to bravely pursue their dreams and move forward steadily. 
Congratulations to all the winners, may this recognition be your strength to move forward.

Accompany your children to pursue their dreams bravely and let your efforts be seen

The world is big and deserves to be explored gently. 
Sanjiu Building Materials is honored to take practical actions to support the children in embarking on a "Sealine Aquarium × Gaomei Ecological Journey" full of learning and laughter during the winter vacation. 
In the Taichung Aquarium, children observed marine life with focused eyes and recorded every new discovery; they walked into the Gaomei Wetland and personally felt the pulse and vitality of the natural ecology. In addition to studying, we also accumulated precious time for each other's companionship and growth through group cooperation, sharing meals and communication. 
We believe that the value of a company is not only reflected in its products and technology, but also in its care and investment in society. 
Being able to accompany children into the world, understand nature, and leave them with a warm childhood memory is the original intention of Sanjiu’s continuous investment in corporate social responsibility. 
In the future, Sanjiu will continue to support more meaningful public welfare and educational activities with actions, so that goodwill can slowly accumulate and continue to spread in society.

The most innocent smile from a child is our most precious feedback

Thank you children for giving back our most precious touch with their smiles&nbsp;
It is a great honor for Sanjiu Building Materials Industry to accompany children to overcome fear step by step and gain confidence and courage&nbsp;
We believe that every well-supported learning can become a force for children to move forward in the future&nbsp;
May this companionship become the starting point for children to continue to bravely move forward&nbsp;

The biggest highlight of this case is the integration of small door design into the folding door. The main door retains the advantage of a large opening to meet the entry and exit needs of equipment, goods and vehicles; the small door is suitable for daily personnel passage, making it more flexible and efficient to use. For the owner, this is not just one more door, but a configuration that makes entrance and exit management smarter: a large door for large entrances and a small door for daily use, taking into account beauty, efficiency and practicality. Key advantages: 1. Daily use is more convenient and movement is more efficient After integrating the small door design, when there are no large equipment or vehicles entering or exiting, people can pass directly through the small door without having to open the entire door every time. This not only makes daily access more convenient, but also makes the overall flow of movement smoother and closer to the actual use situation 2. Reduce door opening and closing and reduce equipment load Separating "daily entry and exit of personnel" from "entry and exit of large equipment/vehicles" can reduce unnecessary frequent opening and closing of doors, reduce equipment usage burden, and help maintain a more stable usage status. 3. Take security control into account and make access management clearer The small door can be used as a fixed entrance and exit for people, making the entry and exit path clearer, and it is also more convenient to use with access control, card swiping or other management mechanisms. At the same time, it can also distinguish the entry and exit needs of personnel and large equipment, improving on-site management order and safety. 4. Keep the advantages of large openings while taking into account aesthetic integration When large-scale equipment, trucks or materials are required to be transported, the advantages of the large-area opening of the top-folding door can still be used to meet the actual needs of industrial buildings. In addition, the overall facade can be integrated with the building's appearance, materials and lines, and the small doors can still maintain a consistent and neat facade effect. ◆Applicable scenarios: Residential, commercial or factory building ◆Can be used with various exterior wall building materials From traditional concrete exterior walls, exterior wall paint, tiles, and marble to today's popular curtain walls, shaped painted corrugated boards, expanded mesh, grilles, and even planted walls, the entire exterior wall can be consistent and have the effect of a hidden door. Whether it is size, color, or material selection, multiple styles are perfectly integrated to realize your architectural design imagination. ◆Customized design, multi-functional options From infrared barrier sensors, smart seizure remote control, fire linkage, small doors for personnel entry and exit, breathable windows, access control card opening, PDLC smart dimming film, etc., we can meet all your needs and create a unique, beautiful and practical door. ■Project name: Quanta International Co., Ltd.
