Explore our certified range of composite sandwich panels and prefabricated structural frames tailored for quick installation, superior R-values, and unmatched longevity in Hanoi's industrial clusters.
The Red River Delta, spearheaded by Hanoi and connected directly through industrial arterials to Bac Ninh, Hung Yen, Hai Duong, and the port city of Hai Phong, is undergoing an unprecedented capital expansion in high-tech manufacturing, pharmaceutical processing, and cold-chain infrastructure. However, Northern Vietnam poses one of Southeast Asia's most challenging microclimates for building envelope engineers: a humid-subtropical regime characterized by extreme summer heat waves exceeding 40°C, direct solar radiation flux, corrosive air contaminants, monsoon typhoons, and the infamous spring "Nồm" weather—a phenomenon where relative humidity consistently hovers between 95% and 100%, generating massive surface condensation on substandard building assemblies.
Standard single-skin metal sheeting or poorly bonded composite sandwich boards fail prematurely under these cyclic thermal-hygrometric stresses. Interstitial condensation causes latent mold propagation, delamination of insulation cores, thermal bridging, and severe corrosion along the structural fasteners. As a dedicated OEM/ODM structural insulated panel (SIP) manufacturer and exporter with more than 15 years of precision engineering heritage, we supply Hanoi's industrial contractors, developers, and steel structure erectors with factory-calibrated, vapor-impermeable insulated envelope systems designed specifically to conquer Northern Vietnam's demanding building physics.
Selecting the optimal core material requires balancing structural load capacities, thermal resistance (R-value), acoustic decoupling, and mandatory fire resistance indices under Vietnamese national technical regulations.

Custom-engineered structural insulated panels deployed across high-growth industrial clusters and urban developments throughout the Hanoi capital region.
Within the booming electronics manufacturing corridor spanning Bac Ninh, Bac Giang, and Hanoi’s Hoa Lac Hi-Tech Park, our tongue-and-groove rock wool and PIR cleanroom sandwich panels provide completely flush, particulate-free wall and ceiling envelopes. Finished with anti-static PVDF or antimicrobial food-grade plastisol coatings, these panels withstand intensive pressurized HVAC regimes while eliminating outgassing.
Strategically situated along the Hanoi–Hai Phong Expressway and around Noi Bai International Airport, temperature-controlled cold storage warehouses demand absolute thermal continuity. Our continuous automated high-pressure PU/PIR panels incorporate heavy-duty eccentric cam-locks, double labyrinth seals, and specialized thermal break gaskets that completely block ambient Red River delta humidity, preventing refrigeration coil frost and reducing compressor electrical load by up to 34%.
For large-span industrial workshops in Thang Long IP, Dong Van, and Pho Noi, our Q355B steel structures integrated with OSB or metal-faced structural SIPs provide immense load-bearing diaphragm capabilities. Additionally, for dense urban districts across Hanoi (such as Cau Giay, Ha Dong, and Hoan Kiem), our lightweight SIPs provide the ultimate solution for structural rooftop additions and modular vertical extensions where existing foundations cannot bear traditional masonry dead loads.
Operating continuously since 2010 with a foundational engineering philosophy centered on structural reliability and thermal efficiency, Joint Star Steel Structure Ltd. has engineered and exported over 352 major pre-engineered building and insulated panel installations for more than 120 institutional clients internationally. Unlike standard sheet-metal brokers, we manage the complete lifecycle: raw steel coiling, high-precision automated roll-forming, continuous polyurethane polycondensation, mineral wool rock-splitting, and automated CNC panel routing.
Our OEM/ODM manufacturing protocols adhere to rigorous ISO 9001:2015 quality management procedures. Every panel batch dispatched to the Hanoi market arrives with mill test certificates (MTC), mechanical adhesive bonding peel test reports (ASTM D903), thermal conductivity verification (ASTM C518), and third-party certified fire endurance testing matching international EN 13501-1 and Vietnamese TCVN specifications.
We solve the critical pain points that multinational project directors face when coordinating offshore fabrication with localized installation in Northern Vietnam:
The construction sector across Vietnam is navigating one of the world's most rapid regulatory evolutions. The introduction and strict enforcement of QCVN 06:2022/BXD (National Technical Regulation on Fire Safety for Houses and Buildings) by the Ministry of Construction has dramatically transformed panel procurement across Hanoi. Fire authorities (Cục Cảnh sát PCCC) no longer permit non-tested, highly flammable cores for industrial factory envelopes.
Our OEM/ODM rock wool sandwich panels utilize natural basalt volcanic rock melted at over 1,450°C and processed into high-tensile, non-combustible fiber cores with automated lamella orientation. This structural fiber configuration achieves exceptional compression strength (up to 150 kPa) while guaranteeing an absolute Class A1 non-combustible rating. For cold chain facilities requiring thermal superiority alongside strict fire compliance, our PIR (polyisocyanurate) formulations utilize special fire-retardant polyols that self-extinguish and produce ultra-low smoke toxicity upon flame exposure.
Simultaneously, multinational electronics and automotive giants investing in Northern Vietnam are designing to green building metrics such as LEED v4 and Vietnam’s homegrown LOTUS rating systems. By utilizing our high R-value SIPs, developers achieve superior building envelope airtightness (reducing building infiltration rates below 0.15 CFM/sq ft), dramatically reducing mechanical chiller sizing, cutting peak grid electricity demand, and earning valuable points toward LEED Gold/Platinum or LOTUS certification.
Direct engineering and commercial answers addressing common questions from general contractors, mechanical consultants, and factory owners in Northern Vietnam.
Hanoi's "Nồm" weather brings sustained relative humidity above 95% combined with warm outdoor airflow contacting cooler indoor air and building surfaces. To stop interstitial and surface condensation, our panels utilize an engineered triple defense system: First, continuous factory-applied internal and external metallic facings (minimum 0.5mm PPGI or 55% Al-Zn alloy) serve as absolute vapor barriers (permeance < 0.01 perms). Second, precision interlocking tongue-and-groove joint profiles incorporate factory-injected butyl sealants and EPDM gaskets that eliminate micro-gaps. Third, our continuous closed-cell PIR or hydrophobic-treated rock wool maintains envelope surface temperatures well above the ambient dew point, completely preventing condensation run-off and mold formation.
Yes. Fire safety approval by Vietnam’s Fire Prevention and Rescue Police Department (Cục Cảnh sát PCCC và CNCH) under standard QCVN 06:2022/BXD requires verifiable laboratory burn testing. We supply our clients with comprehensive international test certifications (including ISO 1182, ISO 1716, ASTM E84, and EN 13501-1 Class A1 / B-s1, d0) along with detailed material datasheets. Furthermore, our rock wool and PIR panel formulations are engineered to readily undergo localized burn chamber testing at authorized Vietnamese testing centers (such as IBST - Vietnam Institute for Building Science and Technology) for formal project-specific burn approval.
Typical fabrication lead time for standard project sizes (3,000m² to 20,000m² of composite panels) ranges between 14 and 25 working days from approved shop drawings. Direct maritime container shipments arrive at Hai Phong Port (Dinh Vu / Tan Vu terminals) within 7 to 14 days of ocean transit depending on port of origin. From Hai Phong, our logistics partners clear customs and coordinate flatbed container trailer deliveries directly to industrial zones in Hanoi, Bac Ninh, or Hung Yen within 24 to 48 hours via National Route 5 or the Hanoi–Hai Phong Expressway (CT04).
As a true OEM/ODM manufacturer, we offer comprehensive customization across all physical properties: panel core thickness from 40mm up to 250mm; core densities tailored from 16kg/m³ EPS up to 140kg/m³ rock wool; skin facers including hot-dip galvanized steel (Z120 to Z275), galvalume (AZ100 to AZ150), 304/316 stainless steel for chemical washdown zones, and structural OSB/3 or MGO for timber-frame modular applications. Exterior coatings include PE, SMP, high-durability PVDF (resistant to intense tropical UV exposure), and specialized anti-static finishes for semiconductor manufacturing.
Hanoi and the northern coastal plains fall into wind pressure zones classified under Vietnamese Standard TCVN 2737:2023 (Loads and Actions). Our panel systems are engineered for high suction uplift and positive wind pressures exceeding 2.2 kPa. We achieve this through concealed through-fixing bolt assemblies with load-spreading saddle washers, reinforced steel tongue-and-groove joints, and engineered span tables that determine precise secondary steel purlin spacing. Full engineering calculation books and fastener pull-out capacities are provided for every client project.
