EVERY QUESTION WE GET, IN ONE PLACE
Pricing, steel grades, timelines, code compliance, rust protection, and on-site welding across Kathmandu Valley — the full answers.
Metal fabrication costs depend on material, weight, design, size, finish, and installation requirements. We provide a free, transparent quotation after reviewing drawings or taking site measurements. Standard mild steel fabrication uses competitive per-kilogram rates based on current Nepal market prices plus labor, primer, and installation. Custom architectural gates and railings are priced per square foot depending on steel thickness, decorative forging, and paint finish. Aluminium structures are priced based on section profile gauge and glass specifications. We provide completely transparent, itemized free cost estimates with no hidden charges.
Yes. We provide fabrication, delivery, on-site installation, and welding services across Kathmandu Valley, including Kathmandu, Lalitpur, Bhaktapur, and surrounding areas. Our service covers Kathmandu metropolitan city, Lalitpur (Patan, Jawalakhel, Imadol, Lubhu, Bhaisepati, Godawari), Bhaktapur (Suryabinayak, Thimi, Lokanthali), Kirtipur, Kalanki, Sitapaila, Balaju, Maharajgunj, Budhanilkantha, and surrounding districts throughout Bagmati Province. Our mobile installation and on-site welding team travels directly to your construction site with complete portable welding equipment and safety gear.
Yes. Our team works with architects, engineers, contractors, and project managers to fabricate structural steel, gates, railings, and other metalwork according to CAD drawings and project specifications. We fabricate heavy structural steel columns, beams, trusses, and baseplates strictly according to architectural blueprints and structural engineering specifications compliant with the Nepal National Building Code (NBC 105 and NBC 205). Every weld joint, bolt connection, stiffener plate, and anchor placement is executed with strict dimensional accuracy and safety load margins.
We source certified prime materials from leading manufacturers in Nepal and international suppliers. Our material inventory includes high-tensile structural steel (Fe 250, Fe 415, Fe 500 grade), hot-rolled mild steel plates, heavy I-beams, C-channels, angle iron, square hollow sections (SHS), rectangular hollow sections (RHS), seamless round pipes, galvanized iron (GI) sheets, commercial stainless steel (grades SS 201, SS 304, and marine-grade SS 316 for rust-free applications), and heavy-duty 6063-T6 architectural aluminium extrusions with powder-coated or anodized finishes.
Yes. In addition to factory workshop fabrication, we offer fully equipped on-site welding and modification services throughout Kathmandu. If you have an existing building requiring structural column reinforcement, earthquake retrofitting, damaged gate hinge repair, railing modification, roof truss extension, or emergency metal repair, our experienced welders arrive on-site with portable arc welding generators, cutting equipment, and safety gear to execute fast, reliable, and secure repairs.
Project timelines vary based on project scope and volume. For residential gates, window grills, and balcony railings, fabrication typically takes 5 to 10 working days from final measurement approval, followed by 1 to 2 days for on-site fitting and installation. Custom metal staircases generally take 7 to 14 working days. Large commercial structural steel frames, warehouse trusses, and industrial platforms are scheduled in phased milestones depending on building readiness. We provide a firm delivery timeline before commencing every job and keep you updated throughout each stage.
Corrosion resistance is vital in Kathmandu Valley's climate due to heavy monsoon rains and high humidity. We implement a rigorous multi-stage surface preparation and protection process: First, all raw steel is mechanically wire-brushed, ground smooth, and degreased to remove mill scale, weld spatter, and oxidation. Second, we apply high-grade anti-corrosive zinc phosphate or red-oxide primer to form a chemical bonding barrier. Third, we apply two coats of premium industrial enamel or polyurethane synthetic paint. For high-moisture outdoor applications, we also provide hot-dip galvanized steel and stainless steel options for decades of rust-free performance.
Yes. Custom staircases are one of our core specialties. We design, fabricate, and install modern central-spine steel staircases, floating cantilevered stairs with hardwood or metal treads, compact space-saving spiral staircases, straight and L-shaped multi-landing staircases, and heavy commercial emergency exterior fire escapes with anti-slip checker-plate treads and sturdy safety handrails. All staircases are calculated for comfortable riser-to-tread ratios, structural load safety, and aesthetic elegance.
Yes, we cater equally to private homeowners building or renovating their residences and commercial clients including hotels, restaurants, schools, shopping complexes, factories, and corporate offices. Whether you need a single decorative safety door for your home or hundreds of tons of structural steel for a multistory commercial building, our workshop treats every project with the same dedication to quality, precision craftsmanship, and dependable service.
Getting started is simple and completely free: You can call us directly or message us on WhatsApp at +977 9851218124, or submit our online contact form with your project details and drawings. We will discuss your requirements, provide initial cost guidance, and schedule a convenient site visit in Kathmandu Valley to take exact laser measurements. Afterward, you receive a detailed, transparent quote detailing materials, labor, finishes, and project timeline with no obligation.
Quality and safety are the foundational pillars of AS Metal Workshop. We have over 10 years of hands-on fabrication experience in Kathmandu. Every welded joint undergoes thorough visual inspection for weld penetration, uniformity, and absence of porosity or undercut defects. Moving components such as sliding gate tracks, heavy-duty ball-bearing rollers, hinges, and locking latches are rigorously tested before delivery. Our installation crews adhere strictly to workplace safety protocols, using proper PPE and secure scaffolding.
