22/06/2023
How do customers evaluate the quality of KH Shield – Vietnam’s leading fire protection solution expert? Throughout the research and development process of KH Shield’s fire-resistant and thermal insulation panels, KH Shield Joint Stock Company has collaborated with many renowned brands nationwide to create products with exceptional fire protection quality. Here are some features and advantages of KH Shield panels as shared by customers.
KH Shield panel – the leading fire protection solution expert in Vietnam, in the application of building ventilation systems.
In terms of applications within ventilation systems such as fire-resistant ducts and fire dampers, KH Shield Corporation has collaborated with Vitduct Corporation since the period before Circular QCVN 06:2021/BXD was issued. Mr. Hoàng Ngọc Chiến – Director of Vitduct Corporation, has made statements about the quality of KH Shield as follows:
Mr. Hoang Ngoc Chien – Director of Vitduct Corporation
“According to the QCVN 06:2021/BXD standard, the requirements for fire resistance of ducts are specified in Appendix A and Appendix D, with 5 specified limits: EI30, EI45, EI60, EI120, and EI180.”
In terms of structure, the fire-resistant ducts meet two criteria: E criterion for material integrity and I criterion for thermal insulation. To achieve these two criteria, Vitduct and KH Shield began their collaboration since late 2019, even before the QCVN 06:2021/BXD standard was issued, to initiate research and testing.
The first test took place in March 2020, approximately 4 months before the QCVN 06:2021/BXD standard became effective. The initial testing encountered many challenges due to its novelty and unfamiliarity compared to prevailing practices in the Vietnamese market. With the concerted effort and determination of Vitduct and KH Shield, the first test met some of the requirements but still could not produce a product that fulfilled all the technical and aesthetic criteria, as well as the most crucial aspect – cost-effectiveness.
Vitduct and KH Shield continued their research and improvement efforts. Following that period, with numerous tests conducted on fire-resistant ducts, Vitduct can be regarded as the most extensively tested brand in Vietnam concerning fire-resistant ducts.”

“By combining the fire-resistant and thermal insulation panels from KH Shield, through precise mechanical processing, we create a fire-resistant product that meets the criteria of durability, aesthetics, water resistance, environmental friendliness, and most importantly, no generation of toxic smoke.”
Outstanding advantages of KH Shield panels with excellent integration capabilities alongside steel materials in construction materials
KH Shield Corporation has collaborated with QH Plus Steel Structure Company to apply KH Shield panels within the protective enclosures of steel structures, achieving remarkable testing effectiveness. Mr. Huynh Tan, Director of Product Development at QH Plus, shared insights regarding the product testing as follows:
Mr. Huynh Tan – Director of Product Development, QH Plus Company
“QH Plus Steel Structure Company is a leading entity in steel structure design, fabrication, and construction in Vietnam. Gaining trust from KH Shield Corporation, they have shared images and information from the fire-resistant enclosure testing session, which achieved an EI 120-minute result.
The research and development team at QH Plus conducted another test on January 14, 2022, to assess the technical capabilities of the fire-resistant panel. This experiment was controlled using three parameters: ignition time, furnace temperature, and temperature on the steel sample. The KH Shield fire-resistant panel with a thickness of 20mm was expected to withstand fire for 60 minutes, and the temperature inside the steel sample was not to exceed 538°C.
At the 30-minute mark, the furnace temperature reached 746°C, and the temperature on the steel sample was 107°C. By the 60-minute mark, the furnace temperature had risen to 1016°C, while the temperature on the sample reached 376°C, meeting the expected results. After 70 minutes, the furnace temperature reached 1053°C, and the temperature on the steel sample was 540°C, prompting the termination of the experiment.”
KH Shield Conducts Effective Testing of Steel Structure Protection Enclosure
Fire-resistant solutions for steel structures are among the crucial components in today’s construction industry. Among these, fire-resistant materials, aside from their fire-retardant qualities, must also ensure various other features such as water and moisture resistance. Mr. Tan further shared:
“Alongside the technical specifications provided by KH Shield, the technical research and development team at QH Plus Company discovered an additional feature, namely the water and moisture resistance of the KH Shield fire-resistant panel.
The technical team conducted an experiment by submerging the KH Shield fire-resistant panel in water. Over a period of 2 hours, the KH Shield fire-resistant panel only had its surface wetted, with no impact on its physical properties. This characteristic is highly suitable for outdoor construction conditions, especially during rainy weather and challenging construction environments.”
The KH Shield panel is utilized in applications for fire-rated and insulated rolling door solutions.
Fire-Rated and Insulated Rolling Door Solution is one of the preferred choices in today’s market. To offer a product that meets standards, manufacturing brands must incorporate high-quality fire-resistant materials and undergo rigorous testing by authorized agencies. With the outstanding advantages of KH Shield panel, Mr. Tran Van Quang – Director of Alumax Vietnam Co., Ltd. – shares the following insights:
Mr. Tran Van Quang – Director of Alumax Vietnam Co., Ltd.
“Alumax Vietnam is delighted to have the opportunity to explore KH Shield products for application in our current fire-resistant steel door and rolling fire-resistant door offerings. One exemplary product with very high practicality is our successfully tested fire-resistant rolling door on January 20th, 2022.
At that time, with advice from KH Shield regarding the KHS 24mm fire-resistant panel, we were initially cautious and decided to test it with the EI 60-minute fire resistance standard. However, even after 60 minutes of burning, there was no impact, and we recommended IBST to extend the time. The results of our testing were successful, reaching 90 minutes. It’s truly remarkable how the KH Shield panel has helped our product exceed our calculations.”
The KH Shield panel is the challenging solution for businesses to overcome the uncertainties of new regulations.
Many partners who come to KH Shield Corporation often encounter a certain level of hesitation when facing new standards for fire safety, such as QCVN06:2021/BXD and Decree No. 136/2020/NĐ-CP. Opting for the KH Shield panel – the leading fire protection solution expert in Vietnam – is the answer to the challenge of enhancing fire prevention, insulation, and meeting the state’s standards. Mr. Vu Quoc Thuy – Director of TMD Mechanical and Electrical Joint Stock Company – shared his thoughts as follows:

Speaking about KH Shield’s products, it hasn’t been on the market for a long time. However, there have been serendipitous connections and collaborations that TMD has engaged in with KH Shield to address complex challenges in the field of fire prevention and firefighting.
As an individual, I have also been directly involved in issues and it took me a whole year to overcome the fire protection solution for elevators. Subsequently, with numerous fortuitous encounters, I have been involved in solving issues for many other projects as well. Up to this day, TMD has resolved nearly 20 projects for elevator manufacturers and constructions involving various types of elevator doors, including E and EI classifications.
Regarding fire protection solutions for elevator doors, it’s not something that can be standardized in terms of a single solution. It’s a combination of various diverse materials. In this context, KH Shield plays a leading role, and both TMD and KH Shield have researched and introduced a dedicated product line for elevators.
KH Shield panels, along with their outstanding features, excel when combined with wood materials.
Not only with steel materials, the excellent compatibility with wood materials is the primary reason for KH Shield panels being the top choice. Speaking about the advantages and features of KH Shield panels when applied to wood materials, Mr. Phạm Hùng Vương – Director of Amavi Construction and Interior Joint Stock Company – shared the following insights
Mr. Phạm Hùng Vương – Director of Amavi Construction and Interior Joint Stock Company
“Similar to a destined encounter, we came across KH Shield panels. Initially, we had concerns about the price as it was relatively high. However, the crucial factor for us, including the leadership, was to find a fire-resistant panel that not only met structural requirements but also facilitated production while satisfying various conditions.
Upon testing KH Shield panels, we discovered numerous advantages. For instance, the smooth surface allows us to apply various types of adhesives (wood adhesives) available in the market. In fact, we currently use some common adhesives that adhere well to KH Shield panels, eliminating the need for specialized adhesives.
Furthermore, the technical adjustments are straightforward. If we want to increase the fire resistance rating according to the EI standard, we simply need to use a different panel thickness.”
Testing the Fire Resistance of KH Shield Panels in the Application of Fire-resistant Wood Doors
”At Amavi, most of our wood cutting machinery uses wood cutting blades, and we also cut KH Shield panels using wood cutting blades as usual. There is no charring at the edges, and the sharpness of the cutting blade as well as the wood cutting lifespan remain unaffected. This has greatly facilitated our production process.
Moreover, when it comes to structural aspects, if needed, we can easily attach handles or KH Shield panels using screws without the risk of screw corrosion. Another crucial factor is that we conducted a burn test (at IBST) and found that KH Shield panels maintain a highly stable structural integrity.
After conducting thorough research, we discovered that KH Shield panels are environmentally friendly and their composition is non-toxic. This aspect holds significant humanitarian value for the investor, ensuring safety for users.
