Exam Details

The Arizona CR-45 Sheet Metal Residential/Commercial Contractor trade exam follows the sheet metal trade exam structure. The exam includes 30 questions, allows 75 minutes, and requires a minimum passing score of 70%. The exam measures trade knowledge related to ducts, chimneys, flues, vents, hoods, ventilation, food service equipment, metal roofing, flashing, architectural metals, gutters, downspouts, and OSHA safety.

The exam content outline includes ducts with 8 items, chimneys, flues, and vents with 5 items, hoods, ventilation, and food service equipment with 6 items, metal roofing, flashing, and architectural metals with 4 items, gutters and downspouts with 3 items, and OSHA safety with 4 items.

Ductwork is the largest portion of the exam outline. Candidates should spend steady study time on HVAC duct construction standards, metal duct, flexible duct, duct pressure class, gauges, reinforcement, sealing, hangers, supports, fittings, transitions, elbows, takeoffs, access, and installation quality. The HVAC Duct Construction Standards, Metal and Flexible, 2005, 3rd Edition is a key reference for this part of preparation.

Because the exam has 30 questions and a 75-minute time limit, candidates should prepare for both accuracy and pacing. Some questions may be answered from practical trade knowledge, while others may require quick reference navigation. Online practice questions can help you build a rhythm for reading each question, identifying the subject, choosing the correct reference when needed, and answering efficiently.

Open Book Test

The Arizona Sheet Metal Residential/Commercial Contractor (CR-45) trade exam is an open-book exam. Candidates are responsible for bringing their own approved references to the examination center. The approved references include SMACNA Architectural Sheet Metal Manual, Code of Federal Regulations - 29 CFR Part 1926 (OSHA), HVAC Duct Construction Standards, Metal and Flexible, 2005, 3rd Edition, International Building Code, 2018, NRCA Roofing Manual: Steep Slope Roof Systems, and Sheet Metal, 2nd Edition.

Open-book testing can help prepared candidates, but it does not replace study. The exam time limit does not allow unlimited searching. Candidates should know where to find duct construction requirements, architectural sheet metal details, OSHA construction safety standards, building code information, steep-slope roofing details, flashing guidance, gutter and downspout information, and sheet metal fabrication topics before test day.

Reference materials may be highlighted, underlined, annotated, and indexed before the examination session. References may not be written in during the exam. Additional loose or attached papers are not permitted with approved references. Permanent tabs are allowed. Temporary removable tabs are not allowed. Candidates may use a silent, nonprinting, non-programmable calculator in the examination center.

For printed or downloaded references, materials should be properly bound before being brought into the testing center. Organizing the approved books before test day can make a meaningful difference because open-book exams reward candidates who know how to use their references efficiently.

Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. Applicants should begin by selecting the correct license classification for the work they plan to perform. For sheet metal work in both residential and commercial settings, the relevant classification is CR-45 Sheet Metal Residential/Commercial.

After selecting the correct classification, candidates should review the examination requirements tied to that license. The CR-45 trade exam is one part of the licensing process. Contractor applicants may also need to complete the Arizona business management or statutes and rules requirement, application requirements, qualifying party requirements, bonding requirements, experience requirements, and other items required by the Arizona Registrar of Contractors.

A practical licensing plan separates exam preparation from application preparation. Exam preparation focuses on ducts, metal and flexible duct standards, chimneys, flues, vents, hoods, ventilation, food service equipment, metal roofing, flashing, architectural metals, gutters, downspouts, sheet metal fabrication, code requirements, and OSHA safety. Application preparation focuses on state forms, business structure, qualifying party information, bond requirements, fees, and supporting documents.

Using online practice questions during the exam preparation phase gives structure to your study time. Questions help reveal which subjects are already familiar and which ones need more review. This makes it easier to use the 3-month access period productively and keeps preparation focused on the subjects most closely tied to the CR-45 sheet metal exam outline.

State Requirements

The Arizona Registrar of Contractors issues contractor licenses by classification. Commercial classifications apply to commercial work, residential classifications apply to residential work, and dual classifications may apply when a contractor qualifies for both commercial and residential work. The CR-45 classification is the residential/commercial sheet metal contractor classification.

The sheet metal classification includes installation and repair of sheet metal, cornices, flashings, gutters, leaders, pans, kitchen equipment, ductwork, skylights, patented chimneys, metal flues, and metal roofing systems. Candidates preparing for the exam should understand both fabrication-related tasks and installation-related tasks connected to these sheet metal applications.

Residential/commercial sheet metal contractors may work with duct systems, ventilation components, architectural sheet metal, roof-related metals, flashing, gutters, downspouts, vents, chimneys, hoods, food service equipment, and related safety practices within the allowed license scope. Contractors should understand where their classification begins and ends. Work outside the license classification may require another properly licensed contractor.

Passing the trade exam is not the same as receiving a license. Applicants are responsible for meeting the full Arizona licensing requirements that apply to the classification, qualifying party, business entity, bond, application, and related state requirements. The trade exam supports the licensing process by testing technical knowledge connected to the CR-45 sheet metal classification.

Test Information and Study Materials

The Arizona CR-45 exam requires preparation across ductwork, chimneys, flues, vents, hoods, ventilation, food service equipment, metal roofing, flashing, architectural metals, gutters, downspouts, sheet metal layout, fabrication, code requirements, and safety. Candidates should study the complete reference list because the exam includes both practical trade knowledge and reference-based questions.

Duct preparation should include metal duct, flexible duct, duct pressure class, reinforcement, gauge selection, transverse joints, longitudinal seams, hangers, supports, sealing, fittings, transitions, branch connections, elbows, offsets, access, vibration, and installation quality. Since ducts account for the largest portion of the exam outline, candidates should become comfortable with the HVAC duct construction reference and how it is organized.

Chimneys, flues, and vents preparation should include metal flues, vent connectors, vent caps, clearances, supports, roof penetrations, flashing around penetrations, corrosion awareness, and coordination with mechanical systems. These topics connect sheet metal work with building safety, weather protection, and proper system performance.

Hoods, ventilation, and food service equipment preparation should include kitchen equipment, hood installation awareness, ventilation components, exhaust ducts, clearances, sheet metal fabrication, grease-related systems, supports, transitions, access, and code-related considerations. Candidates should understand how sheet metal components support ventilation and food service installations.

Metal roofing, flashing, and architectural metals preparation should include roof edges, valleys, counterflashing, base flashing, step flashing, gutters, downspouts, expansion joints, sheet metal panels, fasteners, seams, laps, soldering or sealing awareness, and water-shedding details. The SMACNA Architectural Sheet Metal Manual and NRCA Roofing Manual: Steep Slope Roof Systems are important references for these subjects.

Gutters and downspouts preparation should include sizing awareness, slope, hangers, outlets, elbows, leader pipes, expansion, joints, fasteners, drainage path, and installation details. Gutters and downspouts may seem simple, but they are important for roof drainage and building protection.

Sheet metal fabrication preparation should include measuring, layout, pattern development, cutting, bending, forming, seams, locks, joints, tools, equipment, fasteners, and field installation. Sheet Metal, 2nd Edition supports this part of preparation by reinforcing hands-on fabrication concepts and trade terminology.

Code preparation should include the International Building Code for construction requirements that may connect to sheet metal work, roof conditions, fire-resistance concepts, and building safety. Candidates should become familiar with the organization of the code book so they can locate relevant information quickly during the exam.

OSHA safety preparation should include personal protective equipment, ladder safety, fall hazards, scaffold safety, hand and power tool safety, sharp-edge hazards, material handling, roof work awareness, housekeeping, and general jobsite hazard recognition. Sheet metal work can involve cutting edges, power tools, elevated work, roof work, duct installation, heavy materials, and active construction sites.

Online practice questions help candidates move from passive reading to active recall. When you miss a question, use it as a signal for what to review next. Return to the related reference, study the topic, and answer more questions until the material becomes more familiar. This repeated process can help improve retention and reduce hesitation during the exam.

For open-book preparation, organize approved references before test day. Highlight important sections, use approved permanent tabs, and practice locating information while answering questions. The goal is not to search every answer from scratch. The goal is to understand the sheet metal topics well enough to answer efficiently and use the references when they are most helpful.
