Square, rectangular, and round ducts all have their own advantages, suitable for different site conditions and design requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For M&amp;E contractors, choosing the right type of pipe from the start can help optimize space, facilitate construction, and minimize unforeseen changes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. What types of spaces are square\/rectangular ductwork suitable for?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Square or rectangular air ducts are commonly used in buildings with technical ceiling systems or spaces where height optimization is required.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/05\/z7588658168461_e2ea1c6621b8ede4658a64c822320490-1024x768.jpg\" alt=\"\" class=\"wp-image-5882\" srcset=\"https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/05\/z7588658168461_e2ea1c6621b8ede4658a64c822320490-1024x768.jpg 1024w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/05\/z7588658168461_e2ea1c6621b8ede4658a64c822320490-300x225.jpg 300w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/05\/z7588658168461_e2ea1c6621b8ede4658a64c822320490-768x576.jpg 768w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/05\/z7588658168461_e2ea1c6621b8ede4658a64c822320490-1536x1152.jpg 1536w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/05\/z7588658168461_e2ea1c6621b8ede4658a64c822320490-2048x1536.jpg 2048w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/05\/z7588658168461_e2ea1c6621b8ede4658a64c822320490-16x12.jpg 16w, https:\/\/onggiosaoviet.vn\/wp-content\/uploads\/2026\/05\/z7588658168461_e2ea1c6621b8ede4658a64c822320490-600x450.jpg 600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Common applications include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Office building.<\/li>\n\n\n\n<li>Apartment.<\/li>\n\n\n\n<li>Hotel.<\/li>\n\n\n\n<li>Shopping mall.<\/li>\n\n\n\n<li>Factory.<\/li>\n\n\n\n<li>Technical corridor.<\/li>\n\n\n\n<li>MEP shaft.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A major advantage is the ability to flexibly adjust the width and height to suit the available space.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. When should round ducting be chosen?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Round ducts have a geometric cross-section that facilitates airflow and are commonly used in many ventilation, exhaust, and supply systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In particular, spiral round pipes can be used in locations requiring aesthetics or a uniformly round pipe alignment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sao Viet Air Ducting currently introduces spiral round air ducts with diameters ranging from D100 to D800 mm.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3.

Don&#039;t choose based solely on price.<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A common mistake is comparing the cost per meter of pipe while ignoring the entire system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Consider this:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Quantity of accessories.<\/li>\n\n\n\n<li>Hanging rack.<\/li>\n\n\n\n<li>Installation space.<\/li>\n\n\n\n<li>Labor.<\/li>\n\n\n\n<li>Transportability.<\/li>\n\n\n\n<li>Aesthetic requirements.<\/li>\n\n\n\n<li>Design pressure loss.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">5. Sao Viet Air Ducts can be custom-made to fit each system.<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For large projects, combining multiple types of pipes within the same structure is perfectly normal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The main shaft uses a rectangular tube.<\/li>\n\n\n\n<li>The branch uses a round tube.<\/li>\n\n\n\n<li>Spiral is used in open-air areas.<\/li>\n\n\n\n<li>Specific applications require the use of materials according to specifications.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is no single type of air duct that is absolutely suitable for every project.
