This comprehensive assessment is designed to evaluate candidates' readiness for the Florida Journeyman
Sheet Metal Worker Licensing Exam. The exam measures essential skills and knowledge required for
professional sheet metal work, including HVAC system fabrication, ductwork installation, code compliance,
and safety practices. The multiple-choice and scenario-based structure tests both theoretical understanding
and practical application. Emphasis is placed on real-world decision-making abilities, regulatory compliance
with Florida Building Code and SMACNA standards, and the capacity to solve complex problems encountered
in professional sheet metal installations. Candidates will demonstrate proficiency in material selection, joint
techniques, gauge specifications, and proper use of industry tools.
SECTION ONE: QUESTIONS 1–100
,Question 1
What type of metal is most commonly used for HVAC ductwork?
A. Copper
B. Aluminum
C. Galvanized steel
D. Stainless steel
🟢 C. Galvanized steel
🔴 RATIONALE: Galvanized steel is corrosion-resistant, durable, and industry-standard for HVAC ductwork
due to its zinc coating that prevents rust while maintaining affordability and ease of fabrication.
Question 2
What is the standard gauge thickness often used for residential HVAC ductwork?
A. 10 gauge
B. 26 gauge
C. 30 gauge
D. 12 gauge
🟢 B. 26 gauge
🔴 RATIONALE: 26-gauge strikes the optimal balance between strength and ease of fabrication for residential
ducts, providing sufficient durability without excessive weight or cost.
,Question 3
What does the acronym SMACNA stand for?
A. Standard Metal and Air Conditioning Network Association
B. Sheet Metal and Air Conditioning Contractors' National Association
C. Sheet Metal and Aluminum Contractors' National Association
D. Standard Metal and Air Conditioning Contractors' National Association
🟢 B. Sheet Metal and Air Conditioning Contractors' National Association
🔴 RATIONALE: This is the correct name of the trade association that establishes industry standards for HVAC
and sheet metal work, including duct construction standards used Florida-wide.
Question 4
Which tool is used to cut sheet metal accurately by hand?
A. Hammer
B. Chisel
C. Tin snips
D. Screwdriver
🟢 C. Tin snips
🔴 RATIONALE: Tin snips are specifically designed for clean and precise hand cutting of sheet metal, available
in straight-cut, left-cut, and right-cut varieties for different applications.
, Question 5
What is the standard unit of measurement for sheet metal thickness in the U.S.?
A. Inches
B. Gauge
C. Centimeters
D. Millimeters
🟢 B. Gauge
🔴 RATIONALE: "Gauge" is the standard measure used to specify thickness of sheet metal in the United States,
with lower numbers indicating thicker material.
Question 6
Which method is commonly used to join sheet metal sections permanently in HVAC ductwork?
A. Clamping
B. Welding
C. Tape only
D. Zip ties
🟢 B. Welding
🔴 RATIONALE: Welding provides a permanent, strong joint often required in sheet metal assemblies,
especially for high-pressure systems and commercial applications.
