Hangzhou, Zhejiang Oct 21, 2026 (Issuewire.com) - Modern multi-storey construction requires high performance, strict regulatory compliance, and cost efficiency. Global procurement directors continually seek structural components that compress project timelines without sacrificing safety. Sourcing Comflor 210, Comflor 80 and Bondek AS/NZS-Certified Floor Deck From China (https://www.famoussteel.com/comflor-210-composite-metal-floor-deck-alternative-deep-profiles-galvanized-steel-decking-sheet.html) offers a reliable pathway to optimize project budgets and material supply chains. These composite decking profiles serve as the structural backbone for high-rise commercial and residential projects across the Oceania region. By understanding the engineering capabilities of different section profiles, engineering teams can make informed procurement decisions that improve structural performance. The Geometry of Span: Decoupling Profile Depth from Multi-Storey Temporary Propping Costs Composite floor design relies heavily on geometric properties to determine structural capacity during construction phases. Standard steel decking options often present clear distinctions in cross-sectional geometry, which directly dictates unpropped span limits. Traditional trapezoidal systems like Bondek and standard 80mm re-entrant profiles like Comflor 80 provide reliable performance for typical grid sizes. However, these shallower configurations often require extensive temporary propping when spans exceed certain thresholds. This propping footprint consumes vertical space, delays lower-floor trades, and increases on-site labor expenses significantly. In contrast, deep-nesting profiles like Comflor 210 introduce a massive section modulus to the construction site. This profile features an ultra-deep 210mm rib height, which changes how engineering teams approach large structural bays. The inherent stiffness of this deep profile allows for unpropped spans reaching up to 5.5 meters or more depending on slab thickness. Eliminating temporary propping yields immediate financial and operational advantages for multi-storey projects. Consequently, project managers can accelerate the entire construction cycle. Removing props allows mechanical, electrical, and plumbing contractors to enter lower floors immediately after concrete pouring. Furthermore, this approach reduces the requirement for scaffolding hire and specialized propping labor. Choosing a deep profile over a shallow profile represents a fundamental shift from generic material purchasing to strategic structural optimization. Hangzhou FAMOUS Steel Engineering Co.,Ltd. supplies these varied profiles to match specific bay layouts, ensuring that structural requirements align perfectly with on-site assembly realities. The Slab Mass Equation: Minimizing Dead Loads and Optimizing Fire-Acoustic Ratings The shape of a composite metal deck influences more than just the initial construction phase. It directly affects the permanent volumetric composition of the composite concrete slab. Shallow profiles maintain a uniform cross-section that requires a consistent volume of concrete across the entire floor area. While this provides a dependable structural diaphragm, it adds substantial permanent dead weight to the overarching building frame. Deep-trough designs alter this equation by displacing large volumes of concrete. The high, wide ribs of Comflor 210 act as internal voids within the concrete slab structure. As a result, the system requires significantly less concrete per square meter to achieve the same overall slab depth. This reduction in concrete volume generates a beneficial cascading effect throughout the entire structural design. Lighter slabs mean that the primary steel beams and columns support less dead load. Consequently, structural engineers can downsize the steel sections throughout the building frame. This optimization reduces total structural steel tonnage and shrinks foundation requirements. Therefore, procurement managers achieve compounding material savings across multiple categories. Beyond structural efficiency, these composite systems deliver excellent insulation and safety performance. When manufactured under strict AS/NZS compliance parameters, these profiles satisfy stringent fire and acoustic regulations. The deep profile structure creates a natural barrier against sound transmission, achieving high Rw acoustic ratings. Additionally, the composite action between the profiled steel sheet and the concrete slab provides up to two hours of inherent fire resistance. This performance often eliminates the need for expensive secondary fire-spray applications on the underside of the deck, which further protects the project budget. Floor Zone Synergy: Integrating Composite Decking with Open-Web Steel Joists Maximizing spatial efficiency inside the floor zone represents a critical goal for modern multi-storey commercial designs. Traditional construction methods often stack mechanical service ducts underneath solid primary beams. This arrangement increases the overall floor-to-floor height of the building, which raises facade costs and material usage. A more integrated approach coordinates the floor deck directly with advanced horizontal framing systems. Using composite decking in tandem with specialized open-web steel joists creates a highly efficient floor system. FAMOUS Steel manufactures customized open-web framing solutions that complement both deep and shallow decking profiles. These open configurations allow service pipes, electrical conduits, and HVAC ducts to pass directly through the web openings. This integration creates a highly compact floor zone. When engineers pair Comflor or Bondek profiles with a long-span steel truss joist (https://www.famoussteel.com/long-span-steel-truss-joist-for-modern-commercial-floor-systems-product/), they unlock superior architectural flexibility. This structural combination supports large open-plan office layouts or expansive residential spaces without interior columns. The composite deck provides a rigid upper diaphragm, while the truss joist provides deep, lightweight spanning power underneath. This synergy reduces the total height of the building envelope while maintaining identical interior ceiling heights. For a ten-storey development, saving 200 millimeters per floor removes two full meters from the total building height. This alteration reduces wind loading, saves exterior cladding materials, and lowers heating and cooling demands. By sourcing these integrated components from a single technical partner, procurement teams ensure seamless connection detailing and flawless field installation. De-risking the Cross-Border Supply Chain: AS/NZS Certification, Traceability, and FAMOUS Steel Expertise International procurement requires absolute certainty regarding material compliance and manufacturing standards. The Oceania construction sector enforces strict regulations, including AS/NZS 4600, AS 3600, and AS 2327 building codes. Importing structural steel components requires rigorous quality verification to prevent expensive on-site rejection or structural failure. FAMOUS Steel (https://www.famoussteel.com/about-us/) (Hangzhou FAMOUS Steel Engineering Co.,Ltd.) eliminates these supply chain risks through comprehensive compliance frameworks. Quality assurance begins at the raw material stage. The production process utilizes structural grade galvanized steel coils with certified Z275 or Z350 zinc coating mass.

The presidential office on Thursday refuted media criticism that the chief of the new investigative body attending Cabinet meetings could compromise impartiality and independence in investigations. The response came amid growing media criticism after Kim Ji-yong, chief of the Serious Crime Investigation Agency (SCIA), attended Tuesday's Cabinet meeting for the first time since taking office, despite the long-held practice of investigation chiefs not attending such meetings. In a social media post the previous day, President Lee Jae Myung said chiefs of all government institutions under his command could attend Cabinet meetings, but many media outlets pointed out that such a move could compromise the investigation chief's independence and impartiality in conducting investigations. "The government is strenuously working toward maintaining fairness and political neutrality in investigations and independence in indictments. This principle will remain unwavering going forward," Lee's senior secretary for the press, Seong Ghi-hong, told reporters. The official also made clear that no individua
A joint research team from Soongsil University and Chung-Ang University has developed a technology to disrupt lip synchronization in deepfake videos that use artificial intelligence (AI) to make a person's lip movements match an audio track. Soongsil University said Tuesday that the team, led by professor Choi Dae-sun of its AI Security Center and professor Kwon Jun-seok of Chung-Ang University, developed the technology, dubbed MUTE. According to the team, MUTE is the first technology to disrupt lip synchronization in deepfake videos using audio protection alone. The paper, titled “MUTE: Multi-Level Alignment Uncoupling Against Talking-Head Exploitation for Voice Protection,” was accepted for presentation at the Conference on Neural Information Processing Systems (NeurIPS) 2026, one of the world’s leading AI conferences. The study was conducted as part of a research and development project supported by the Personal Information Protection Commission and the Korea Internet & Security Agency (KISA).

INCHEON — The suspect behind last week's stabbing spree in Incheon has tested negative for psychopathy, police and legal sources said Thursday. The Incheon Metropolitan Police Agency conducted a psychopathy test on the 59-year-old suspect, Choi Choong-rak, but his score fell below the 25 out of 40 points needed to classify him as a psychopath. Choi is accused of attempting to kill 10 people at a commercial complex in Incheon, west of Seoul, on Oct. 13, by wielding knives in both hands. The rampage left eight people injured, including one who remains unconscious after suffering cardiac arrest. The two others escaped without harm. During police questioning, Choi said he carried out the attack out of anger over medical treatment he received at a local hospital. He also told police that he did not target specific people but chose those who looked weaker than him. Choi has 10 prior convictions, including two for attempted murder. Police said they are analyzing evidence and conducting further investigations to determine his motive and whether the attack was premeditated.
An appeals court on Thursday ruled against U.S. private equity firm Lone Star Funds in its suit against the Korean and Seoul city governments to return a combined 168.2 billion won ($125.9 million) in taxes. The Seoul High Court handed down the ruling against Lone Star after the Supreme Court returned the case to the appeals court for review in April last year. The Texas-based firm had earlier filed the suit against the state and the municipality, seeking the return of withheld taxes in connection with profits from its investments in Korea. Lone Star and affiliate firms purchased large shares of Korea Exchange Bank, Kukdong Engineering Construction and Starlease between 2002 and 2005, and made huge profits by selling some of the shares in 2007. They paid smaller taxes than local companies would have, citing the tax treaty that Korea has with Belgium where the company that made the investment was based. The National Tax Service (NTS) levied additional corporate taxes against Lone Star and its entities, offsetting them with withheld taxes. Lone Star then filed a suit seeking cancellation of
LG Electronics is taking its smart factory technology beyond manufacturing and into renewable energy, partnering with Korea Water Resources Corp. to develop artificial intelligence systems for one of the country’s largest power facilities.

The system could help forecast electricity output, simulate operating scenarios and diagnose equipment conditions, enabling operators to identify problems and assess performance before m
Orion has expanded production lines for its flagship Custard cream cakes across Korea, Vietnam and India to keep pace with surging domestic and international demand, the company said Thursday. Launched in Korea in 2004, Orion Custard is a soft, individually wrapped sponge cake with a custard cream filling. It has become the company’s second-biggest global pie brand after its flagship Choco Pie. Global sales rose 14 percent last year to 154 billion won ($116 million). China, Vietnam and India accounted for 76 percent of that total, and sales kept growing at a double-digit pace through September this year. The company added a production line in Korea in September and recently began running new lines in Vietnam and India. The expansion lifts Custard’s global production capacity to as much as 300 billion won a year, roughly double last year’s sales. Orion’s global research center at its headquarters in Korea oversees product development for each market. In Vietnam, the company sells flavors including tiramisu, raspberry, egg lava, melon and a reduced-sugar version. There is also a fl
A court on Thursday ruled against Young Poong Corp. in a shareholder derivative lawsuit seeking 837 billion won ($631 million) in damages from Korea Zinc Co. Chairman Choi Yun-beom and other company directors. Young Poong — a major shareholder in Korea Zinc — had filed the suit in November 2024, claiming Korea Zinc's directors had inflicted losses of 837 billion won on the company by making a tender offer involving the purchase of its own shares at 890,000 won apiece, when the actual price was around 560,000 won. The Seoul Central District Court ruled, however, that Korea Zinc's directors could not be deemed to have violated their managerial duties, given the steps they took before making the purchase. It also ruled that the action did not violate the Commercial Act or the company's articles of incorporation.
