Why Sri Lanka in 2026
Sri Lankan HVAC work comes from four places: export factories, tourism, healthcare, and the commercial and residential towers rising in Colombo. No single one carries the market, so a shop that serves two or three of them is safer than one that depends on a single contractor.
Apparel and other factories
Apparel and textiles remain the largest export sector. The Export Development Board put 2025 apparel and textile exports at about USD 4.91 billion, up 5.34%, in figures reported by the Daily Mirror; total exports were about USD 17.2 billion. Sewing floors, cutting rooms, finishing halls and offices in these plants need ventilation and air conditioning, usually as long rectangular supply and return runs.
Hotels and tourism
Tourist arrivals reached a record 2.36 million in 2025, and about 1.69 million visitors arrived from January to September 2026, around 2% below the same period last year. Hotels, resorts and restaurants need air conditioning and kitchen extract whatever the monthly count does. We did not find a reliable public figure for the hotel construction pipeline, so we do not quote one; ask the main contractors on your list what they have coming.
Colombo Port City and city towers
Colombo Port City is a special economic zone on 269 hectares of reclaimed land. Daily FT reported in January 2026 that construction had started on Bay One Residences, a 231-apartment project of about USD 112 million, the first residential development in the zone. In October 2026 Home Lands reported that piling on its Central Park Boulevard project was complete. Towers like these mean air handling rooms, corridor and car park ventilation, and smoke extract, all in sheet metal. Treat each project as a lead to follow, not a sure order book, because schedules move.
Healthcare
Government hospital projects are the third source. Reports in 2026 describe a planned National Heart Centre at the National Hospital in Colombo, a cancer unit under construction at Badulla Teaching Hospital, and a relocated Base Hospital at Deniyaya for which India has pledged equipment grant support. Operating theatres, isolation rooms and laboratories need tightly sealed, often stainless ductwork; see our cleanroom duct guide and galvanised vs stainless comparison. Public projects also tend to move slowly, so check funding and award dates.
Standards and codes for ductwork in Sri Lanka
We could not find a Sri Lankan duct construction standard that replaces the international documents. In practice a duct shop builds to what the consultant's specification names.
- Energy efficiency building code: the Sri Lanka Sustainable Energy Authority publishes a code of practice for energy efficient buildings, with a ventilation and air conditioning section. It drives design airflows more than duct construction, but it rewards tight, well sealed ductwork; see our air leakage classes guide.
- SMACNA, ASHRAE, CIBSE and similar: consultant specifications may name SMACNA for gauges, seams and joints, and ASHRAE or CIBSE for design. We did not find a public source showing which is most common in Sri Lanka, so ask for the specification. See our international standards comparison, the gauge chart and the hangers and supports guide.
- SLSI: the Sri Lanka Standards Institution issues the national SLS standards. We did not find an SLS standard for sheet metal duct construction, but SLS 1259, for example, sets the nominal supply voltage (see the power section below).
Importing duct machinery into Sri Lanka
- Layered charges: a JETRO guide lists customs duty, VAT, the Social Security Contribution Levy, CESS and the Port and Airport Development Levy among the charges on imports, depending on the tariff line. Its worked example uses VAT at 18% and SSCL at 2.5%.
- Reforms in 2026: summaries of Budget 2026 describe customs duty bands of 0%, 10%, 20% and 30% from April 2026, and Daily FT reported in March 2026 that Cabinet approved a phased removal of CESS, with CESS rates cut by 50% from 1 April 2026 and the rest phased out by 2029. We could not read the rate line for HS 8462 machinery, so we do not quote a figure.
- What to do: ask a licensed customs broker to classify the machine and confirm the current duty, CESS, SSCL and VAT. Sri Lanka Customs publishes a national import tariff guide with a column for SLSI related requirements, so ask the broker whether any approval applies to your machine. Schemes for export-oriented producers exist, but a duct shop serving local contractors may not qualify, so check.
Machines usually ship by sea to Colombo, the country's main container port. Tell us the port and delivery address when you request a quotation. Our importing guide covers the general paperwork.
Power supply: 50 Hz, 230/400 V
Sri Lanka's mains frequency is 50 Hz. According to the regulator's voltage discussion paper, Sri Lanka Standard SLS 1259, based on IEC 60038, gives a nominal system voltage of 230/400 V. That means 230 V single phase and 400 V three phase. Our machine pages list 380 V, 50 Hz, three phase; tell us your measured workshop voltage and we wire the motors, drives and control transformer to suit. If your site sees voltage dips or interruptions, say so, because PLC controlled lines and hydraulic units run better on a stable supply. See also duct machine voltage and frequency by country.
Typical Sri Lankan shop set-ups and the machines that fit
Contractor shop, rectangular duct for factories and fit-outs
Start with the Rectangular Duct Line II SBAL-II or the Auto Duct Line SBAL-III. Both take 1250 or 1550 mm wide coil, form 0.5 to 2.0 mm sheet and feed up to 18 m/min. Add a Pittsburgh lockformer (SBLC series) for 0.4 to 1.2 mm Pittsburgh seams and 0.7 to 1.5 mm snap lock, a TDF flange forming machine for 0.5 to 1.5 mm sheet depending on model, and a pneumatic folder (SBWS series, up to 0.4 to 1.5 mm on the 1500P) for fittings and short pieces. That covers straight duct, TDF joints and simple fittings with a small crew.
Volume shop for apparel campuses, hotels and towers
Shops chasing factory campuses or tower packages need output and consistent quality over thousands of square metres. The Auto Duct Line SBAL-V runs from coil to finished panel on 0.5 to 1.5 mm sheet at up to 18 m/min. A duct zipper closes TDF duct seams on 0.8 to 1.5 mm sheet, and the hydraulic folder (SBWS-1.5-1500H up to 2.0 mm, SBWS-1.2-2000H up to 1.5 mm) handles heavier gauge and longer bends.
Corner parts and fittings
The Auto Corner Making Machine blanks corner pieces at 40 to 120 pcs/min on 0.8 to 1.2 mm sheet, and the Pneumatic Corner Mounting machine SBCC inserts corners into TDF flanges up to 1.5 mm. A Plasma Cutter SBPC1550 cuts fittings and flat parts from 0.4 to 4 mm sheet on a 1550 mm wide table, 4000 or 5000 mm long, so elbows, transitions and offcuts do not need hand marking.
Round duct
Spiral duct suits exposed ceilings, plant rooms and industrial extract. The Spiral Tubeformer SBTF-1500 makes Φ80 to Φ1500 mm duct in 0.4 to 1.2 mm galvanised, the SBTF-1602 goes to Φ1600 mm and 0.4 to 1.3 mm, and the SBTF-2020 reaches Φ2500 mm and 0.4 to 2.0 mm galvanised. The Spiral Duct Flanging Machine SBFB-1600 turns flanges on round duct ends. For a real example, see Kavanagh Industries in Sydney, which added an SBTF-1602 in October 2026.
Labour and space
We did not find a reliable current figure for sheet metal wages in Sri Lanka, so we do not quote one. The general case for automation is the same everywhere: an auto duct line replaces much of the manual marking, cutting, notching and folding, so a small crew can supply several sites and quality does not depend on one skilled worker. Ask for an output comparison on your own duct sizes.
On space, the auto duct line is the longest item, with the coil rack at one end and a run-out table at the other. Ask us for a layout drawing based on your building before you sign a lease, and leave room for coil deliveries, finished duct storage and truck loading. In a hot, humid coastal climate, keep coil off the floor and out of the open; galvanised coil stored in damp conditions can develop white rust. Our factory layout guide has worked examples.

FAQ
Which ductwork standards are used in Sri Lanka?
We could not find a separate Sri Lankan duct construction standard. The Sri Lanka Sustainable Energy Authority publishes an energy efficiency building code of practice with a ventilation and air conditioning section. Beyond that, a duct shop builds to the documents named in the consultant's specification, which may be SMACNA, ASHRAE, CIBSE or another recognised standard. We did not find a public source showing which one dominates, so ask for the specification before you quote or buy coil.
What voltage and frequency do duct machines need in Sri Lanka?
Sri Lanka's mains frequency is 50 Hz. Sri Lanka Standard SLS 1259, based on IEC 60038, gives a nominal system voltage of 230/400 V, which means 230 V single phase and 400 V three phase. Our machine pages list 380 V, 50 Hz, three phase, so no frequency change is needed. Tell us the three phase voltage measured at your workshop and we wire the motors, drives and control transformer to suit.
What duties and taxes apply when importing duct machinery into Sri Lanka?
Sri Lanka's import charges can include customs duty, VAT, the Social Security Contribution Levy (SSCL), CESS and the Port and Airport Development Levy, depending on the tariff line. Budget 2026 summaries describe customs duty bands of 0%, 10%, 20% and 30% from April 2026 and a phased cut in CESS, and a JETRO worked example uses VAT at 18% and SSCL at 2.5%. We could not read the rate line for HS 8462 machinery, and rates are changing, so ask a licensed customs broker to classify the machine and confirm the current charges before you budget. We do not quote a rate here.
Where is ductwork demand in Sri Lanka coming from in 2026?
The main sources are apparel and textile factories, hotels and resorts, hospital building, and commercial and residential projects in and around Colombo, including Colombo Port City. Apparel and textile exports were about USD 4.91 billion in 2025 according to Export Development Board data reported by the Daily Mirror, and tourist arrivals reached a record 2.36 million in 2025.
Do I need SLSI approval to import a duct machine?
We could not confirm whether Sri Lanka Standards Institution (SLSI) inspection or approval applies to duct forming machinery. Sri Lanka Customs publishes a national import tariff guide with a column for SLSI related requirements on each tariff line, so your customs broker can check the line that applies to your machine. Taokron machines are CE marked with a Declaration of Conformity and ship with electrical diagrams and component lists.
Which machines should a new Sri Lankan duct shop start with?
A shop making rectangular duct for factories, hotels and commercial buildings usually starts with a rectangular duct line or auto duct line, a Pittsburgh lockformer, a TDF flange former and a folder. Add a duct zipper for seam closing, corner machines as volume grows, a plasma table for fittings, and a spiral tubeformer when round duct becomes regular work. Send your duct sizes, gauges and monthly output and a Taokron engineer will propose a machine set within 12 hours.
