Explore Our Double-Primed Moulding &
Trim Collections
Our mouldings are factory-finished with a two-coat primer system. This precise coating process delivers a smooth, uniform surface, ensures superior paint adhesion, and reduces on-site prep time.
Baseboard
Baseboard Trim is available in Primed MDF, Finger-Jointed Pine, and custom profiles, with standard widths from 3-1/4" to 7-1/4". The pre-primed surface goes straight into finish painting after installation, helping projects cut on-site processing time while keeping floor-line trim consistent across unit types.
Crown Moulding
Crown Moulding spans Flat, minimalist, and traditional decorative profiles. Builders can standardize crown proportions and style across a community without sourcing new matching profiles for every unit type.
Casing
Interior Casing is available in Primed MDF or Finger-Jointed Pine, while Exterior Casing comes in moisture-resistant PVC. We offer a range of standard casing profiles, including WM623, WM433, and WM356.
Shoe Moulding
Shoe moulding & quarter round for a clean baseboard finish. It conceals the expansion gap, cut-line variance, or uneven edges between the baseboard and the floor.
Door Frame
We offer four types of door jambs — Single Rabbet, Double Rabbet, Flat, and Split — that can be pre-matched to your door schedule and wall conditions. Different jamb profiles correspond to door positioning, sealing, and wall-thickness needs, avoiding on-site frame modifications, extension jambs, or re-cutting.
Wall Moulding
Chair Rail, Panel Moulding, Wainscot, and Shiplap combine into a complete wall trim system. Standardized profile combinations build out wall detailing while reducing on-site design guesswork and multi-batch material sourcing.
From Baseboard, Casing, and Door Jamb to Crown Moulding, UWG can confirm profile, material, size, and quantity across every category based on your schedule, moulding takeoff, or project drawings — and deliver a factory-direct project quote.
Backed by UWG's warehousing and dealer network in Houston and Oklahoma, standard SKUs support fast restocking; custom profiles are handled by the same team from drawing confirmation through sampling and bulk production, keeping the first batch and every batch after it consistent in profile, size, and finish.
Moulding & Trim Sizing Guide (Baseboard, Casing, Crown & More)
Every project has different profile and dimension requirements. Below is a quick reference to our most common moulding types — Full PDF technical drawings, dimensional specifications, and product documentation are available upon request. Contact our team to receive the files.
Width is the primary sizing variable for most trim selections; exact thickness, length, and profile should be confirmed against project drawings and installation requirements.
For door jamb sizing, standard North American wall thickness is set by the stud (2x4 or 2x6) plus drywall thickness, which is why 4-9/16" (2x4 wall) and 6-9/16" (2x6 wall) are the most common sizes. Interior mouldings are typically MDF or finger-jointed pine, while exterior components such as brick mould are more often PVC, finger-jointed treated pine, or LVL for weather resistance. On length, our experience shows builders typically choose 12' or 16' lengths based on ceiling height (standard 8' ceiling vs. high ceiling) to minimize seams and improve visual quality. Our Moulding & Trim Buying Guide can help you choose the right trim dimensions for your project.
| Moulding Type | Thickness | Width | Length |
|---|---|---|---|
| Casing | 7/16" - 5/8" | 2-1/4" - 3-1/2" | 7' / 8' / 16' |
| Baseboard | 7/16" - 11/16" | 3-1/4" - 7-1/4" | 8' / 10' / 12' / 16' |
| Crown | 9/16" - 3/4" | 3-5/8" - 7-1/4" | 8' / 12' / 16' |
| Shoe | 1/2" - 3/4" | 1/2" - 3/4" | 8' / 12' / 16' |
| Wall | 5/8" - 3/4" | 2" - 3-1/2" | 8' / 12' / 16' |
| Door Frame | 3/4" | 4-9/16" / 4-13/16" / 6-9/16" | 6'8" / 7' / 8' |
| Brick Mould | 1-1/8" | 2" | 7' / 8' / 17' |
| Exterior Casing | 3/4" - 1" | 3-1/2" - 5-1/2" | 8' / 10' / 16' |
Moulding & Trim Materials: MDF vs PVC vs Finger-Joint Pine vs LVL
Different projects have different requirements for moisture resistance, dimensional stability, and budget control. We offer a full material matrix spanning Finger-Joint Pine moulding trim, MDF moulding trim, PVC trim moulding, and high-strength LVL moulding. The technical comparison below helps you match the right grade of material to your specific application — an objective technical evaluation that supports project quality while keeping costs under control.
| Selection Criteria | Finger-Joint Solid Wood | MDF | PVC | LVL |
|---|---|---|---|---|
|
|
|
|
|
| Best Use Cases | Interior exposed trim, solid-wood look, or stained finishes | Standardized residential projects in dry interior areas | Around exterior doors/windows and damp areas like bathrooms, basements | Door jambs, flat stock, and long-length trim runs |
| Moisture Performance | Moderate — needs sealed edges and finish-coat protection; not recommended for prolonged moisture exposure | Below average — not recommended for continuously damp areas | Excellent — 100% waterproof, moisture-proof, and insect-proof | Strong — less prone to warping and cracking than solid wood |
| Dimensional Stability | Depends on the quality of the finger-joint process | Consistent indoor profile, flat and even surface | Won't warp from moisture, but longer lengths need allowance for thermal expansion/contraction | Laminated structure is more stable — helps reduce door jamb warping and dimensional drift |
| Purchase Cost | Mid to high | Lower — well suited to large-volume standardized purchasing | Mid to high | Moderate |
| Recommended For | Custom projects / builder whole-home customization | The primary choice for standardized products | Coastal/high-rainfall projects, around bathrooms | Door casing/trim applications with high stability requirements |
Based on our experience working with many builders, the ideal approach is a "zone-based material specification" strategy: use cost-effective MDF for dry interior wall areas to optimize overall budget; use Finger-Joint Pine or LVL for door and window casing, which see frequent stress and need strong nail-holding power; and mandate zero-water-absorption PVC for exterior areas and high-humidity bathrooms to eliminate rot-related callbacks entirely — delivering the best overall balance of long-term building durability and total project cost. See our Trim Material Guide for details.

Moulding & Trim Styles Guide: Craftsman, Colonial, Modern & Victorian
The architectural character of a space isn't set by the floor plan alone — it's directly shaped by the profile shape of your trim styles moulding. Below is our guide to moulding profiles by style.
| Style | Profile Character | Best Fit Categories |
|---|---|---|
| Craftsman | Straight lines, square edges, minimal curvature | Casing, Baseboard |
| Colonial | Multiple stacked curves, full-bodied profile | Casing, Baseboard, Crown Moulding |
| Contemporary / Modern | Flat, minimal, no carved detail | Baseboard, Wall Moulding |
| Victorian | High-relief, multi-layer ornamentation | Crown Moulding, Wall Moulding |
| Fluted | Vertical groove texture | Casing |
Craftsman & Colonial Style Trim & Casing
In traditional North American single-family home development, craftsman door casing stands out for its signature square edges and straight geometric lines, delivering a pure structural aesthetic well suited to interiors that call for a clean, crafted feel. Colonial door casing and matching baseboards, by contrast, use multiple stacked curves for a full-bodied profile. This richer cross-section brings a formal, classic architectural atmosphere to a space. To make sure these complex curves come together perfectly, we hold tight tooling tolerances during manufacturing to guarantee flush miter joints on site. For detailed selection parameters on these two classic styles, see our complete door casing styles and profiles guide.
Modern & Contemporary Moulding & Trim
For high-end open-plan residences or minimalist commercial spaces, removing visual clutter is the core design goal. Standard modern door casing strips away all carving and curvature in favor of clean flat stock and square edges. Paired with equally low-profile, flat modern baseboards, this combination softens the transition between wall and floor and stretches the visual continuity of the space. Whether you need pre-primed MDF or solid-wood contemporary trim moulding, we deliver the flatness precision that ensures a crisp, minimalist finish. For more on minimalist specs and sizing, see our baseboard styles guide.
Victorian & Fluted Profiles
Specific historical character calls for precise profile detail to recreate it. For historic renovation projects or interiors emphasizing classical elegance, victorian trim moulding uses deep grooves and multiple layers of high-relief ornamentation to reproduce traditional richness and grandeur. For wide door openings or interior structural columns, fluted trim moulding adds continuous vertical texture, greatly enriching the play of light and shadow on the surface without adding physical bulk.

Why Builders Choose UWG as Their Wholesale Moulding & Trim Supplier
UWG doesn't just offer a broad product lineup — we're committed to engineering-grade supply chain optimization and technical support that gives your project trim solutions balancing cost competitiveness with ease of installation.
Quality Control & Packaging
Throughout production, we strictly monitor moisture content and material grade to keep trim dimensionally stable through long-distance shipping and climate changes. We continuously check profile consistency and coating quality during manufacturing so that components like casing or baseboard fit tightly with no visible color mismatch at installation. Every shipment also goes through AQL inspection and batch-number verification; moisture-proof wrapping, corner protection, and professional container loading minimize the risk of damage, so material arrives ready to go straight into an efficient installation process.
Lead Time & Project Delivery Support
For high-frequency categories like baseboards, casings, and crown mouldings, we maintain local inventory in the U.S. for rapid replenishment, while our standard moulding profiles can be shipped from the factory within as little as two weeks. This flexible supply model provides a reliable restocking buffer throughout your project. Whether you encounter on-site material loss or last-minute quantity changes, you can replenish quickly without the long delays typically associated with overseas production and ocean freight. The result is fewer work stoppages caused by material shortages, while reducing upfront inventory investment and minimizing on-site storage requirements.
Direct-to-Site Wholesale Trim Moulding Advantage
UWG has rebuilt the traditional trim supply chain. Unlike the conventional model, where multiple layers of dealers and big-box retail markups add cost at every step, we run on a decentralized supply chain logic. This model removes middleman costs directly, so the wholesale trim moulding you receive comes with a more competitive pricing structure — putting more of your project budget into the quality of the trim itself.
Reducing On-Site Moulding Installation Risks
Backed by our expertise in breaking down trim profile structures, every piece of baseboard trim or casing is rigorously engineered to solve the toughest sizing-mismatch and finishing challenges on site. We provide technical guidance from drawing-spec confirmation through trim matching, minimizing schedule delays from on-site cutting or rework and letting your installation crew work at maximum efficiency.
Moulding & Trim Sourcing Guide for Builder
Shoe moulding is thinner, more flexible, and ideal for modern interiors with clean lines, while quarter round is thicker and more rounded, making it better suited for traditional styles or covering larger gaps.
Door trim, also called door casing, frames a doorway both functionally and decoratively. Key components include the casing (hides gaps between jamb and wall), jamb (structural frame for hinges), stop (prevents over-swing), and optional backband, rosett
A door frame is the structural framework that supports and holds the door in place, while door casing is the decorative trim that covers the space between the wall and the frame.
When choosing crown moulding, match the size to your ceiling height for balanced proportions. For ceilings under 8 feet, use 2½–4" mouldings to avoid a cramped look. Standard 8-foot ceilings suit 3–5¾" sizes, while 9–10-foot ceilings can handle 4¼–7" mouldings. Ceilings over 10 feet may use mouldings
