Buying things online has become the default for almost everything, and building materials are no exception. Some contractors turn to online building supplies because the pricing beats what the local yard can offer. Others simply want the convenience of ordering from a job site trailer instead of driving across town. And sometimes, a specific product just is not stocked nearby, so an online marketplace for building materials becomes the only realistic option.
For years, this was not really practical. Lumber, rebar, and other heavy construction materials are expensive to ship, so most contractors relied on the local hardware store, lumberyard, or a distributor for anything beyond a handful of items. Local suppliers were, and in many cases still are, the fastest way to get materials on site.
That is changing quickly. What started as a handful of hardware chains posting their catalogs online has grown into a full ecosystem of online construction material sellers, from national retailers to wholesale-only platforms built specifically for builders. Below is a rundown of the ten most useful online sources for building materials in the US right now, along with what each one does well and where it falls short.
Why Contractors Are Shifting Toward Online Building Supplies
Before getting into the list, it helps to understand why this shift is happening. Where do contractors buy materials today, and why has that changed?
- Price comparison is easier. A contractor can check pricing across several building material suppliers in minutes instead of calling around.
- Delivery to the job site saves time. Many platforms will ship heavy or bulky construction materials directly to the site, cutting down on truck trips.
- Access to specialty items. Local stock is limited by shelf space; online construction material sellers can carry far more SKUs, including hard-to-find sizes and fittings.
- Bulk ordering and account pricing. Many suppliers offer contractor accounts with volume discounts, which matters when purchasing house construction materials at scale.
With that context, here are the ten platforms worth knowing.
1. Home Depot
Home Depot remains one of the largest and most familiar names in building materials online. It operates as a warehouse-style home improvement store and lumberyard, serving both homeowners tackling a weekend project and contractors sourcing materials for a full build.
Home Depot’s online catalog is actually larger than what most physical stores can stock on their shelves, covering everything from framing lumber to specialty fasteners. Orders can be picked up locally or shipped straight to the job site, which makes it a flexible option whether you need something today or are planning a delivery for next week.
Strengths: Broad inventory, nationwide store network, flexible pickup or delivery. Watch for: Popular items can sell out locally during peak building season.
2. Lowe’s
Lowe’s is Home Depot’s closest competitor and offers a similarly wide range of building materials, tools, and home improvement products. The two chains overlap heavily, but Lowe’s carries some different brands and often runs its own promotions, which can make it worth checking both before placing a large order.
Through Lowes.com, buyers can purchase lumber, roofing, flooring, rebar, steel components, and appliances in a single order. Lowe’s has built a strong reputation for customer-focused service, and many orders qualify for free delivery to a store or directly to a work site.
Strengths: One-stop shopping, competitive pricing, strong delivery options. Watch for: Stock levels and available brands can vary by region.
3. Menards
Menards has a smaller physical footprint than Home Depot or Lowe’s, but it ships nationwide, so location is less of a limiting factor than it used to be. It functions as both a lumberyard and a general building supply store, making it a solid fit for residential projects and smaller commercial jobs.
Beyond raw materials, Menards stores also sell appliances and rent out equipment, and the company has enough of a presence in Canada to be useful for contractors working projects near the border.
Strengths: Competitive pricing, equipment rental, cross-border shipping. Watch for: Not geared toward large-scale commercial or industrial projects.
4. Do It Best
Do It Best is one of the largest hardware store cooperatives in the country and leans more toward the DIY customer, though it is still useful for contractors placing smaller bulk orders, such as boxes of screws or fasteners.
With locations in every US state, orders can be picked up locally, shipped to a nearby branch, or delivered to a job site. The trade-off is a lighter selection of heavy-duty building materials compared to the big warehouse chains, so it works best for smaller projects or supplemental orders rather than a full material list.
Strengths: Nationwide footprint, fast turnaround on smaller items. Watch for: Limited selection of heavy structural materials.
5. Ace Hardware
Ace Hardware has a store in nearly every community, and its online ordering system connects directly to local store inventory. That means the online catalog reflects what your nearest Ace actually carries, rather than a separate national warehouse.
The real advantage is convenience. Local hardware stores often keep shorter hours, but the website lets you place an order at any time and pick it up the next day if the item is in stock. For a crew that runs into a supply gap mid-project, this kind of quick-turnaround ordering can keep a job moving.
Strengths: Local availability, fast pickup, helpful in-store staff. Watch for: Smaller catalog and generally higher prices than big-box chains.
6. True Value
True Value works similarly to Ace: you place an order online, then pick it up at your local store. True Value will also ship online-only or out-of-stock items to your chosen location, which slightly expands what is actually available to you compared to shopping in person.
The product range leans toward standard hardware, tools, and household items rather than heavy construction materials, which makes True Value best suited for smaller orders and everyday job site needs.
Strengths: Simple ordering process, good for routine supply runs. Watch for: Selection is not as deep as national warehouse retailers.
7. Hardware World
Hardware World is a purely online supplier operating out of a single warehouse, with no local pickup option. What it lacks in convenience, it makes up for in selection, particularly for hard-to-find hardware and unusual part sizes that most local stores simply do not stock.
It is worth noting that Hardware World does not carry appliances, and shipping is not free, so those costs and lead times need to be factored into any estimate before ordering.
Strengths: Deep inventory of specialty and hard-to-find items. Watch for: No local pickup, shipping costs and delivery time add up on large orders.
8. SupplyHog
SupplyHog.com takes a hybrid approach that sets it apart from most other building material suppliers. Lightweight items like screws and metal studs ship directly from SupplyHog, while heavier materials such as lumber are fulfilled through a local delivery partner. This model helps control shipping costs on bulky items while still offering the convenience of a single online order.
SupplyHog also carries appliance parts and finishing materials, though not full appliances. For contractors juggling a mix of small hardware and bulky structural materials, this combined model can simplify procurement.
Strengths: Smart mix of direct shipping and local delivery for heavy items. Watch for: Delivery speed depends on the local partner network in your area.
9. BuildDirect
BuildDirect is a true online-first, wholesale-focused platform that sells directly to builders rather than routing orders through local retail stores. Large or expensive orders can ship straight to the job site, and in some cases, materials are sent directly from the manufacturer.
The catalog is narrower than the big warehouse retailers, focusing mainly on flooring, decking, siding, and kitchen or bathroom finishing materials. That makes BuildDirect a strong choice specifically for finishing-stage house renovation materials, though most projects will still need a second supplier for framing, structural, and general building materials.
Strengths: Wholesale pricing, manufacturer-direct shipping on bulk orders. Watch for: Narrower product range; plan ahead since large orders take longer to arrive.
10. Amazon
Amazon carries an enormous range of building products, some shipped from its own warehouses and others fulfilled directly by third-party sellers. Because of that mix, it is worth double-checking where an item is shipping from and the expected delivery window before relying on it for a time-sensitive order.
Amazon tends to shine for smaller hardware, fasteners, fittings, and specialty items that are otherwise hard to track down, and pricing is easy to compare across listings. For large or heavy construction materials, though, delivery times and shipping costs can make it a less practical choice than a dedicated building supplier.
Strengths: Massive selection, easy price comparison, fast shipping on eligible items. Watch for: Inconsistent delivery times on bulky items from third-party sellers.
How to Choose the Right Supplier for Your Project
With this many options, picking the right source for a given order comes down to a few practical questions:
- What are you ordering? Structural materials like lumber and rebar often make more sense from a warehouse chain or wholesale platform, while small hardware is easy to source from almost any of the retailers above.
- How fast do you need it? Local pickup through Home Depot, Lowe’s, Menards, Ace, or True Value beats waiting on shipping when a job is already underway.
- Are you buying in bulk? Wholesale-focused suppliers and contractor accounts often unlock volume discounts that retail pricing does not offer.
- Do you need mill certifications or documentation? For structural or commercial work, confirm that a supplier can provide proper certification paperwork before placing a large order.
- What is your budget? Comparing a few sources before committing to a large purchase is one of the simplest ways to control the overall cost to build a house or complete a renovation.
Take the Guesswork Out of Material Purchasing
Comparing pricing, checking stock, and matching specifications across ten different suppliers takes real time, time that most contractors would rather spend running their crew than researching vendors. This is where an accurate material takeoff makes a real difference. Instead of guessing at quantities and hoping the numbers hold up, a detailed estimate tells you exactly what to order and how much of it you need before you ever visit a supplier’s website.
Digital Estimating helps contractors and builders put together precise material lists and cost estimates for residential and commercial projects, so purchasing decisions are based on real numbers rather than rough guesses. Whether you are sourcing from a national chain or a wholesale-only platform, having an accurate takeoff in hand makes every one of the suppliers on this list easier to work with.
Frequently Asked Questions
Where do contractors buy materials most often?
Most contractors still rely on a mix of local warehouse chains like Home Depot, Lowe’s, and Menards for everyday needs, supplemented by online-only or wholesale suppliers for bulk orders, specialty items, or better pricing.
Are online building materials more expensive than local stores?
Not necessarily. Many online construction material sellers offer competitive pricing, especially on bulk orders, and some platforms provide volume discounts that local stores cannot match.
Can I get bulk discounts when buying building materials online?
Yes. Many suppliers offer contractor or trade accounts with pricing based on order volume, material type, and purchase frequency, which can meaningfully reduce the overall cost of a project.
Is it better to buy building materials locally or online?
It depends on the material. Heavy structural items are often easier to source locally to avoid shipping costs and delays, while specialty hardware, finishing materials, and bulk orders frequently make more sense through an online supplier.
How do I know if I’m buying the right amount of material?
The safest approach is to work from a professional material takeoff or estimate rather than guessing quantities, since ordering too little causes delays and ordering too much wastes money.
