Roof Trusses
Prefabricated trusses offer a quick, precise, and resource-efficient alternative to conventional stick framing. Our roof trusses are produced under strict quality controls to ensure they meet your design specifications and deliver a structurally sound, long-lasting roof framing solution.
- All roof trusses are engineered to comply with local government building regulations.
- Trusses are manufactured from premium-grade lumber and durable steel connector plates.
- We provide truss configurations in sizes suited to most residential construction projects.
Floor Trusses
Floor trusses provide an advanced floor framing system for builders and homeowners. They can span greater distances than traditional joists while leaving open chases for efficient installation of HVAC, electrical, and plumbing services. Homeowners enjoy floors that meet or exceed code-required deflection limits, deliver quiet, squeak-free performance when installed correctly, and allow for larger open layouts than conventional framing.
- Engineered specifically to meet your project’s load and stiffness criteria.
- Constructed with high-quality 2x4 framing lumber for strength and consistency.
Floor Trusses
Floor trusses provide a high-performance framing option for builders and homeowners alike. They can span greater distances than conventional joists while creating open chases that simplify the installation of HVAC, electrical, and plumbing systems. Homeowners enjoy floors that meet or exceed code-required deflection limits, stay quiet when properly installed, and allow for more open-concept layouts than traditional framing.
- Precisely engineered to match your project's required loads and stiffness.
- Manufactured with premium 2x4 framing lumber for consistent strength.
Wall Panels
Prefabricated wall panels help lower both labor and material costs while maintaining robust structural performance. Compared with walls framed entirely on-site, factory-built wall panels deliver tighter quality control, more uniform construction, and a smaller environmental footprint.
- Designed and built to meet or exceed all applicable local and national building codes.
- Cut down on on-site framing time and reduce labor expenses.
- Delivered to your jobsite ready for rapid installation and finishing.

Alongside our prefabricated components, we carry a wide range of dimensional lumber, including standard framing and treated options in the sizes, grades, treatments, and species required for residential builds. Our lumber is responsibly sourced, and strict quality checks ensure you receive reliable material so you can keep projects moving without interruption.
- Top-quality Spruce-Pine-Fir (SPF), Treated #1 Southern Yellow Pine (SYP) 2x, #2 SYP Timbers 4x 6x, and Structural Douglas Fir.
- Offered in a variety of dimensions with lengths up to 20' (26' available by special order).
- Premium-grade studs: 2x4 and 2x6 in common wall heights.

Engineered Wood
Engineered wood products play a central role in modern building, delivering strength, consistency, and resource efficiency. We stock multiple engineered wood options suitable for both interior and exterior applications.
- LVL, a high-strength engineered wood, is ideal for beams, headers, and columns thanks to its resistance to warping and efficient manufacturing, providing a long-lasting alternative to conventional lumber.
- I-Joists, valued for their light weight and load-carrying capacity, are widely used in residential and commercial framing. Their distinctive "I" profile, combining laminated veneer lumber or solid sawn lumber with plywood or OSB, delivers economical, dependable support for floors, roofs, and ceilings.
- Rim boards, a key element in floor framing, align with floor joists to create a unified floor system. Produced from materials such as plywood or LVL, they help transfer loads and maintain structural integrity while guarding against moisture-related issues.
- LSL, part of the structural composite lumber family, offers outstanding strength and dimensional stability for a variety of uses, relying on resource-efficient processes to outperform many traditional lumber products.
- PSL, another structural composite lumber, combines high strength with an appealing appearance. Its use of smaller-diameter trees, often Douglas fir, makes it a sustainable solution for beams, headers, and columns.
- OSB offers excellent value and a strong strength-to-weight ratio, making it well suited for demanding load-bearing sheathing applications.
- CDX Fir Plywood, recognized for its toughness, is a reliable choice for subflooring and other structural lumber & trusses applications.
- ZIP System Roof and Wall Sheathing integrates the strength of OSB with a built-in weather barrier, delivering durable protection for walls and roofs.
- AdvanTech subflooring provides exceptional stiffness, moisture resistance, and fastener holding power, and when paired with its adhesive, helps create a solid, squeak-resistant floor system.

Frequently Asked
'Truss & Framing' Questions
For residential framing, builders most commonly use SPF (spruce-pine-fir) or Douglas fir due to their strength-to-weight ratio and dimensional stability. SPF is often more economical and works well for most interior framing, while Douglas fir is stronger and preferred for longer spans or higher loads. When choosing, consider the required span, load, and whether the lumber will be exposed to moisture. Always check grade stamps for structural use and consistency in quality.
How does the Central Illinois climate affect which exterior lumber and truss materials I should use?
The freeze-thaw cycles and seasonal humidity swings in Central Illinois can cause lesser-quality wood to warp, crack, or rot if not properly treated. For exterior applications, pressure-treated lumber or naturally durable species like cedar are better at resisting moisture and decay. Engineered wood products used in trusses are designed to remain stable with changing temperatures and humidity when properly enclosed. Always pair the right material with proper flashing, ventilation, and finishes to extend service life.
Dimensional lumber is solid sawn wood (like 2x4s and 2x10s) and is widely used for studs, joists, and rafters because it’s readily available and easy to work with. Engineered lumber, such as LVLs, I-joists, and laminated beams, is manufactured for greater strength, consistency, and longer spans with less warping. Engineered products are ideal where you need open floor plans, fewer support posts, or to carry heavy loads. The choice often comes down to span requirements, budget, and design flexibility.
For garages and pole barns in the Pontiac area, pre-engineered roof trusses with treated bottom chords or protective coatings can help manage occasional moisture and condensation. Common designs include fink or attic trusses for garages and scissor or mono trusses for pole barns, depending on desired ceiling height and storage needs. Snow and wind load requirements must be factored into the truss design, which will influence lumber size and connector types. It’s important to provide accurate building dimensions and intended use so the right truss configuration and materials can be specified.
When choosing treated lumber, check the treatment rating (such as above-ground vs. ground-contact) and match it to how the wood will be used, especially for posts and joists. Look for clean, straight boards with minimal splits and a uniform treatment penetration, especially on cut ends. For decks, many people use treated framing with a higher-end surface like composite decking or cedar for improved appearance and comfort. Always seal cut ends with an appropriate end-cut preservative to maintain protection against rot.
Roof trusses should be stored flat and supported evenly to prevent bowing, and they should be lifted by the joints or top chords rather than by a single web or plate. During installation, temporary bracing is critical to keep trusses plumb and aligned until permanent bracing and sheathing are installed. Follow the truss placement diagram and manufacturer’s bracing details closely, using only approved fasteners and connectors. Avoid cutting or drilling truss members, as even small modifications can compromise structural integrity.
