REBAR FABRICATION
Rebar Fabrication
Reinforcing steel is fabricated in our plant to shop drawings and bar lists, then delivered to site — solving the shortage of yard space and skilled labour on urban sites and cutting rebar loss.
BACKGROUND
Why fabricate rebar in the shop
With skilled rebar workers harder to find and labour costs rising, contractors increasingly need mechanised, specialised fabrication plants. Hansung Precision reduces rebar loss while improving quality, material control and schedule.
- Public clients demand high-quality rebar work under standardised systems
- Larger buildings require planned fabrication; pre-fabrication shortens the site schedule
- Avoids complaints and environmental restrictions on urban sites
- Site fabrication makes material storage difficult; in the shop, scrap is recycled and loss minimised
Objectives
- Precise construction and fabrication from shop drawings
- Accurate placing drawings and bar lists
- Optimised bar quantities — minimum loss, lower labour and material cost
Placing and fabrication drawings become shop drawings, enabling precise pre-fabrication. Design, fabrication and assembly are managed together.
Rebar placement — the core of structural work — is executed completely, securing quality control.
MARKET
Shop fabrication in Korea
Advanced economies fabricate over 95% of rebar in plants. Since 2002 Korea has shop-fabricated about 10% of annual demand (1.0–1.2 million tonnes), and major contractors are reviewing company-wide adoption.
Overseas — 95%+ shop fabrication
- Standardised design drawings
- Worsening site conditions
- Tight work space, rising labour cost, cost pressure, environmental issues
Korea — about 10% of demand
- 1.0–1.2 Mt/yr shop-fabricated of 10–12 Mt national demand
- More than doubled since 2002
- Rising steel cost, labour shortage, large urban projects, environmental issues
- About 50 fabricators nationwide
Barriers
- Lack of confidence in cost savings
- Concern about schedule disruption
- Concern about adapting to site changes
- Competition with formwork/rebar subcontractors and their site relationships
