Material prices below are national averages; availability in New York City may shift costs slightly.

Material	Cost/Unit	Pros	Cons	Best For
Dimensional Lumber (2x or 3-ply)	$10-$20 per linear ft materials only	Lowest cost, widely available, easy to work with, no special equipment needed	Limited span capability, susceptible to moisture and decay, not appropriate for long spans	Short window and door headers under 6 feet in non-critical applicationsLowest cost, widely available, easy to work with, no special equipment needed
LVL (Laminated Veneer Lumber)	$25-$50 per linear ft materials only	Stronger than dimensional lumber, stable and consistent, handles longer spans, available in standard sizes	More expensive than dimensional lumber, must stay dry, not attractive for exposed applications	Standard window and door headers, floor beams, and most residential beam replacementsStronger than dimensional lumber, stable and consistent, handles longer spans, available in standard sizes
Glulam (Glued Laminated Timber)	$30-$60 per linear ft materials only	Excellent strength-to-weight ratio, attractive natural wood appearance, available in very long spans	Requires protective finish if exposed, longer lead times for custom sizes, higher cost than LVL	Exposed beams in living spaces, long spans in open-concept designs, architectural applicationsExcellent strength-to-weight ratio, attractive natural wood appearance, available in very long spans
Steel I-Beam (W-Shape or Wide Flange)	$50-$150 per linear ft materials only	Maximum strength for span, does not rot or warp, slim profile for long spans, permanent solution	Requires skilled welders or bolted connections, heavy equipment often needed for placement, more expensive	Long basement spans, load-bearing wall removal projects, or where headroom is very limitedMaximum strength for span, does not rot or warp, slim profile for long spans, permanent solution
Parallel Strand Lumber (PSL)	$35-$65 per linear ft materials only	Very high density and strength, handles heavy point loads, consistent performance	More expensive than LVL, less common and fewer contractor familiarity	Column and post replacements, heavy point-load applicationsVery high density and strength, handles heavy point loads, consistent performance
